DPReview posted studio images from the R6

This allowed me to download full size raw and jpg files for 100, 1600 and 6400 ISO. I opened these up in Lightroom, well I couldn't open the R6 files yet. So I resized the R6 jpgs to the same resolution as the R files to allow a comparison in compare screen mode in LR.
First observation, when comparing jpg vs jpg I was surprised with the shadow noise on the people's faces under their chins with the R files at 160 and 6400 ISO. The Asian woman had colour blotches (colour noise) that I haven't experienced with the R. So then I compared the RAW R files with the R6 jpgs. This showed that the shadow blotches largely disappeared. Very disappointed in the quality of the DPReview jpgs for the R.
Anyway, when comparing the images:
- The R6 images were noticeably more pink when looking at the people's faces, even after I set the colour picker at the central grey square to neutralise colour casts. In my view, the pink was unpleasant I would normally correct this.
- At 100 ISO the R images are noticeably sharper than the upsized R6 files. No surprise here. I didn't see any improvement in dynamic range with the R6, but this would be best comparing RAW with RAW.
- At 1600 ISO, the R6 files are slightly cleaner when comparing jpgs, but the R is better when I compare the CR3 file. I prefer the rendering of the R on the faces.
- At 6400 ISO, the R has noticeably more colour noise, but when I compare the CR3 file, the R colour noise largely disappears. Although there is more grain in the R CR3 file, I far prefer this to the R6 jpg which has more colour noise.
This showed that there is only limited value of comparing the DPReview jpg files, so I will have to wait until LR / ACR are updated to allow the processing of R6 RAWs.
Nevertheless at 100 ISO, the R files are sharper - no surprise.
I expect quality differences to be less at 1600 ISO and the R6 to be better at 6400 ISO.
I shot an event last night with the R (and 5DsR) often using the R at 6400 ISO so this is a critical value for me. The R is substantially better than the 5DsR at 6400 ISO even when downsized, so I prefer to shoot with the RAW (also better AF). I do not find myself limited by the R files at events, but expect the R6 to be better. I look forward to comparing RAWs.
