The vast majority of people don't know what sRGB or DCI-P3 or color profiles are, or care about it. I understand that you may be frustrated about bad support, but it is just not that big of a deal for most people. That said, color management and HDR support for wayland is being actively worked on, and I wouldn't be suprised if it works better on wayland than X11 in a year or two. Also the distro suggested here (linux mint cinnamon) uses X11, not wayland. I agree with OP that we shouldn't scare people away from linux. Forcing people to have an opinion on X11 vs Wayland or color profiles, definately could scare them away.
