Of course it does, no argument. The argument is that the process of
handling the display is being made far more complicated than it has to be,
probably to sell features. The point is, Photoshop doesn¹t care if the
display is profiled to a target, it just needs a profile to account for
this, to a point of course!
Most profile using setups don't allow the outgoing white point of the
transformation to be chosen, even though this is theoretically possible
using the absolute colorimetric information in (ICC version 2) profiles.
[Too bad if you have ICC version 4 display profiles though, since they
don't do absolute colorimetric anymore!]. By default, the Operating System
and application CMM's will use a relative colorimetric or perhaps perceptual
rendering, so you get whatever white point and brightness is native to the
display when it was profiled. A calibration facility allows choosing these
aspects, and doing so with (generally) much greater precision than an ICC
profile. So I'm not sure that setting up a display can be made a whole lot
simpler than the current calibrate/profile arrangement, and most of
the commercial tools hide these steps in a single pass anyway.
