I have no clue if I did this correctly....
I opened the same .CR2 raw file in both LR4 RC2 and DPP. File of course taken with a 5D3. Both zoomed in at 100% and just compared the 2 images side by size.
Exactly the same raw file but they look different when opened in each application. From sharpness and color!
I did a similar test yesterday and came to similar but disturbing conclusion. I first did the raw comparison like you did and knowing the initial raw treatment can be different i tried to play with the LR file to see if i could make it as sharp as the dpp file after the fact. I could never match the sharpness look and feel of the dpp version. I then decided to create a tiff file from both system after optimizing the setting like i always do and trying to get the most out of the picture.
Again the tiff from dpp was much sharper!?!? Wtf!?!?
Sorry i dont have sample here to post but i did notice this difference seem to be even greater at higher iso. While i think Lr is much better at NR then dpp, maybe that process on high iso file bring some form of softness as well, in comparison to the NR process from the dpp software.
Even leaving the files flat, shooting in neutral picture style and applying no adjustment to the files, the conclusion was that the dpp was sharaper, just like wshinji file here...
I even downloaded the RC version 2 update for lr4 and i get the same result...
