Better check your system setup
 - some monitors reported different profiles
You may experience inconsistent color rendition between color managed applications

How can it be that “the X atom and colord returned different profiles” when the profiles are clearly the same?

For context, I am running Debian 13 with colord, xiccd, and i3wm. If further information is required, I’d be happy to provide them.

It is comparing different names for the profile, you should be good.
