Well, to the VM the combined display + graphics card behavior appears as 
the current display behavior. So the reported EDID to the the VM - in my 
understanding at least - represents the display connected to the VM (not 
to the host system). I agree that the change for building a profile 
within the VM would probably be rather subtle.
