brvideo Is there any chance you have issues with certain colors? Probably not or you would have noticed in the past?
I believe I have some issues with colors as well, independently of dithering. I tried to figure out if one color bothers me more than others by using the colored overlays typically employed to assess the Irlen syndrome, but I did not make much progress. Recently I was told that I have a bit of chromatic aberration. I struggle focusing on a green or a red background - I forgot which color. I had never received this feedback before.
