I found this thread after searching for my particular problem. I have a brand new M2 12.9 that has a pronounced green shift when scrolling white text on a black background. I first noticed it when reading and in the Apple website which has a lot of white on black graphics. I felt that there was something off with the display immediately. It looks fine with a static image but seems confused and presents eye strain with video. I notice some slight jelly scrolling, which I had not seen on the old M1 Pro.
If I do the skanskew test at testufo.com the white lines go to a pale green blue. It looks awful next to an M1 12.9 Pro.
I'm running the latest iPadOS 16.6 and had tried the 17 beta but no difference. Truetone or Nightshift make no difference either.
