It does have very slightly lower noise, but that is not the reason it's a darker image which is what leads to the difference in our perception of color and contrast.
Again I'll note that with color NR the 7D II ends up looking a tiny bit cleaner, i.e. lower luminance noise. But in the end neither requires a different work flow or more work. Neither has "better data."
My perception is a bit different and I tend to agree with Jrista.
My comparison of RAW samples (no NR at all - no Chroma no Luminance NR) at DP comparison tool which I posted a bit earlier shows that at ISO3200 NX1 RAW samples visually look better/cleaner/crisper than ones from 7Dm2 and as I also noted NX1 noise pattern is visually better and more pleasant than noise pattern of 7Dm2. NX1 is less blotchy , has a bit more higher noise frequencies and a bit more regular - so should be easier to clean up compared to 7Dm2 . Blotchy noise pattern from many Canon Cameras is something that was always irritating me as well as low performance at low contrast details in red channel - just smearing them away. 1Dx fortunately is better in this respect though also suffering a bit.
Also on this samples NX1 is not downsampled/normalized to 7Dm2 resolution which would also add more difference in favor of NX1.
I was interested to see if NX1 could compete with A7S - but so far A7S is far ahead of all the competitors.
Just see here as an example one of test picture done handheld by A7S in extremely low light conditions at ISO20000.

Color noise in the 7D2 samples cleans up completely, with no loss of detail, using CNR in ACR. This is true for the NX1 as well.
Cleaning up luminance noise, no matter how random/fine, is always a trade off involving noise and detail.
jrista said:I have exactly the opposite experience. Per-pixel color noise isn't difficult...the real difficulty with color noise is the blotches...the stuff that spans 50-100 pixel areas. I believe Neutral knows what I'm talking about. It shows up in shadow areas and at high ISO, and it is nearly impossible to clean up without obliterating detail. I've tried using TGVDenoise as well as several multiscale noise reduction routines on it within PixInsight, and it is just NOT easy to clean up, and impossible to clean up without a visible cost to detail (due to it's scale...you have to factor in large pixel areas, so of course it's going to affect detail.)

This is what surprised me about the comparison I posted above, the 7D2 is on the left and the NX1 is on the right. From the DPReview low light samples what I'm seeing is that at 6400 (and 12.8K although I didn't post it since the NX1 seems to fall apart more significantly over 6400) the 7D2 definitely looks worse before chroma noise reduction but then the 7D2 looks considerably better after a small amount of chroma noise reduction.

Are you reducing the noise on Neutrals screen captures? If so, the NX1 has been downsampled. Reduce noise at full size then downsample, and no matter what you do to the 7D II, the NX1 still look better.

I applied the standard chroma noise reduction to the RAW files and then downsampled to JPGs. The 7D2 definitely looks better at 6400 and 12800; the NX1 has a kind of funky quality to the noise.
jrista said:I noticed a slight amount of something when I denoised the 6400 and 12800 images. Not sure what that is. Hopefully it is simply very early versions of the demosaicing support for the NX1 files in ACR/LR.
I have been testing out CaptureOne Pro. CaptureOne does seem to render a better quality noise with Canon files than LR does. I'm not going to say it's groundbreaking, but it doesn't seem to exhibit that horrid blotchy color noise that I loath so much in my Canon files with Lightroom. Sadly, C1 does not seem to have any support for Samsung cameras...![]()
I am beginning to think now that Adobe's algorithms in Lightroom are indeed becoming rather dated. They don't render the data in the RAW files as well as they could be. I don't remember who asserted that in the past, but I think they may be right. Here's to hoping Lightroom 6.x gets a much-needed rewrite of the rendering pipeline, one that eliminates the color blotch with Canon files.
I did notice that LensRentals.com now has the NX1 on preorder:
http://www.lensrentals.com/rent/compact/samsung/samsung-nx1
Woo! Not sure that I'll have a chance to try it out before the end of the year, but I'm glad they have it. They have a number of lenses as well. I think I'd give the NX1 and the 16-50 a try at the very least...but since this is something I'm curious about as an alternative to a 7D II for birds, I may hold off until Samsung releases their 300mm f/2.8 lens first. One thing I did learn recently is there do not seem to be teleconverters for the NX line mount yet. That might be an issue for me...if I picked up the 300mm f/2.8 lens, I would want both 1.4x and 2x teleconverters, and not having them would probably be a deal breaker. Maybe if Canon lenses AF well on the NX1 with an adapter...but I suspect that wouldn't be the case for a while. :'(

I know they've had the NX1 up for pre-order for at least a month or two as I almost tried to order one for testing before an event I shot over the thanksgiving weekend.

As for the weird NX1 noise, I can definitely believe that it could have something to do with the LR conversion although I'm not quite sure how DPReview arrived at their DNG files. The craziest part of those results to me is that before color noise reduction the NX1 definitely looks better but after you remove the color noise the 7D2 looks better, at least to my eye. I don't think I've ever seen that happen before. I've seen cameras become essentially equal after you remove the color noise but never swap positions like that.
jrista said:Personally, the large blotchy color left behind after your regular color noise reduction is what bugs me the most. There is very little that can clean that up nicely. If Adobe could fix their RAW engine to NOT produce that in the first place, then one of my biggest complaints about Canon RAW images would be gone. They still wouldn't have the dynamic range, but, at least the data would be cleaner. I don't really want to spend the couple hundred bucks on C1 Pro, as it's workflow doesn't seem as nice to me as Lightrooms, and it has a limited range of DSLR compatibility...but I may jut do that for the IQ.

I know exactly what you mean, this was the issue i had with the A7 at high ISO. I'm not sure I saw anything like that in the 7D2 samples I played with but I'd need to check again. Do you see this on the 5D3 as well or just 7D2 samples?
