This means that the GCM would have to change a bit more: GCM must know
what the native monitor gamma is.

Such an information can be taken from the ICC profile, either supplied
by the user, created with GCM and colorimeter or created with GCM and
"eye-measured" calibration.

The lack of eye-measured calibration is already reported as bug 605019
https://bugzilla.gnome.org/show_bug.cgi?id=605019

which also refers to a tutorial how ColorSync on Mac did it:
