I can't see any reason why he would think that your display is set to D93
from your profile. The v2 ICC profile is rather loose spec-wise about
storing white points. Some developers choose to add the white point tag
adapted along with the primaries (D50), others add the tag unadapted (D65
ish in your case). Since there is not even a chad tag in the profile I'm not
sure how he'd ever get D93 from it. Perhaps he is using some software what
automatically adapts the 'wtpt' tag to from D50 to D65, perhaps giving
something like D93 as a result in this case? I can't for the life of me see
any logic in this though.
For the record, Eizo Colornavigator reads the profile as having D65ish white
point, as well, and the primaries look like they should for your display
adapted from D65, not D93.
Hope this helps,
Sam Berry
