Well, a monitor profile loads a calibration AND the profile when
selected.
It's likely that the image viewer isn't using the profile - just
throwing the image at the calibrated screen. Whereas Photoshop uses the
profile [which describes the calibrated monitor and adjusts the image
that last few percent].
The calibration must be pretty harsh to push an LCD screen all the way
to D50. I'd be trying the native white point - or 6500 if there isn't a
native option [too many display calibration app's in the last few weeks
to remember which has exactly what options.]
Again basICColor Display will almost certainly handle this better than
the rather basic Match. More options. Blatant plug:: To save searching,
you can get it from me. [note iOne Display (new one) support not yet
available in BICC Display]
Most users find that D65 screens match reflective images illuminated by
D50 lamps, although this is certainly one area where differences in
personal perception become apparent.
Although viewer A may agree with viewer B that print 1 and 2 match and
that screen 2 and 3 match when it comes to print and screen match
viewer opinion is very subjective.
Viewer A may think that a 5000 lightbox is matched to a 5500 screen,
wheres viewer B may observe a better match at 6500.
Thus the championing of different white points - choice is somewhat
dependent on room light levels and it's what looks right that is right
in monitor white point choice - as long as you're matching a print /
proof in the correct viewing light.
does this answer the question?

this is a bit confused, see above.
