I have the following problem:
When shooting towards a sky with a lot of purple/pink/orange to blue colour transitions Capture One 11, 12 and 20 BETA all produce a pink arc with RAW files from my Nikon Z7.

The problem occurs with every single RAW file that contains said transitions. A (not very usable) fix for this problem is to change the ICC profile to another camera. Changing it to the D850s ICC profile for example makes the issue mostly disappear. When I set it to Adobe DNG Workingspace the issue totally disappears. There is also a similar banding issue when there is a transition from greyish to purple. Because of said "solutions" my guess for the Z7 ICC profile is that C1 interprets the colours in a wrong way and because of that gives me those banding artifacts. As i am (understandingly) not happy with the banding issues that C1 produces with my RAW files, I hope that there will be a solution and fix for the ICC profile soon. If I can assist you further or you need the RAW files of the sample photos that I attached I can send them to you.
Best regards,
Othmar
