More serious and real question, does X11 support actually measuring and calibrating colour? I know you can apply ICC profiles but I was under the impression that the actual calibration tools were usually used under macOS or Windows with profiles exported to Linux.

To the same level that Wayland does - it doesn’t actively do anything for or against it. There are tools that happen to be built for X11, and which you can also use on Wayland (with a very small amount of additional manual steps vs. how it works on X11)
