It's unfortunate that colour calibration took a while to be fully implemented (xx-color-management-v4 landed on most compositors half a year ago I think, though LTS distros may need to wait longer to get it).
That being said, thanks to Nvidia I never got colour calibration to work right in X11 either, so I have no horse in this race. Would be cool to finally get HDR working for the first time, but I don't know if that'll ever happen on Linux with Nvidia hardware. Guess I should keep dual booting for HDR content until either Windows 10 dies off or I get new hardware.
I do actually notice the lack of tearing in Wayland, especially under heavy load. Used to annoy me to no end to see my windows tear when just dragging them across a 1080p screen. I don't know if it was an Intel driver bug (I tried all the config settings) or something X11 specific, but Wayland did finally fix the tearing issues I had.
I haven't noticed any problems with colours in either Gnome or Gamescope (except for the lack of HDR, of course, but that's also true on X11) so whatever is causing issues for you seems to be DE specific. Looks like we both have issues other people never encountered, that's what makes graphics stacks so impossible to debug and code for.
