GIMP uses GTK+.

GTK+ uses Cairo APIs for rendering to the screen.

Cairo APIs assume 8-bit sRGB.

Therefore in GTK+ applications such as GIMP, images must be converted to
sRGB before they can be displayed on the screen.

Cairo is just one part of our eco-system which is following the
guidelines of how to integrate with color management even if you do it
badly; assume sRGB.

so that means, that specifying a monitor profile in GIMP’s preferences other than sRGB will result in 
displaying wrong colors. Or am I wrong?

I didn’t know that.

On systems with builtin desktop CM, like OS X, wouldn’t it be better to disable the choice of a monitor 
profile in GIMP at all, as long as cairo assumes SRGB?
