Wayland seems to have problems showing colors properly. I was trying to fix this issue myself a couple weeks ago.

Colors in Xorg and Windows(gross) show properly, Wayland always looks dull and muted in comparison. Switching color profiles didn’t change anything.

But hey, maybe there’s a fix I haven’t tried yet that works… I sure would hate to be proven wrong! No seriously, if someone has a fix for the dull colors I would likely start using Wayland again.
