A big chunk of the complaints are because Wayland's support for better than X11 colour management has taken a very long time to go from proposal to something that's stable and ready to implement.

Note, though, that a heck of a lot of the difficulty here is that X11 worked by assuming that you have a fixed framebuffer that correctly represents the data sent to the RAMDAC that then drives your CRT, and required hardware to emulate that as we moved away from CRTs and 13W3 connectors, while Wayland wants to work with things like hardware composition (where the final display output is created on-the-fly in hardware from multiple framebuffers, saving energy), and displays whose EOTF can be controlled by software.
