It's still effective, actually. It's simply the case that when the monitor
profile is selected in the proof setup dialog box (with the "preserve color
numbers" option checked) something in the nature of a "null transform"
occurs: the monitor profile that the CPU uses to drive the display is
identical to the profile that is being simulated in the proof setup.
The result is also identical to what is displayed when simply assigning the
profile to the image file, as you do mention. But it's incorrect to think
that activating this type of proof setup simulation makes the monitor
profile "ineffective."
Best regards.
