That would certainly explain it.

I was wondering about that. Right now, that's the behavior.

But if you had two identical images differing only in color profile, 
should the same action (say, "increase contrast by 30%") deliver
	(a) the same visual result (gamut permitting), or
	(b) the same RGB values?

Wouldn't (a) be preferable, even if it is different from current behavior?
