I think I just found a “bug” in wayland color management: if you are using wayland, at the moment the best strategy is to profile only and let the app such as darktable do the color management, since no graphics program can yet communicate with the wayland color management engine. However, if you also need calibration curves, because e.g. your laptop screen has a color cast and it’s not possible to fix the color cast with the osd of the screen, at the moment there is on way to apply the calibration curves only in wayland, and let darktable do the rest.
