I'm simply opening each in Photoshop's "Custom" dialog within the Color
Settings and both the white point (D50) and primaries reported are
identical.
Gamma 1.8
White Point D50 (x 0.3457, y 0.3585)
The (relative) x and y values are the same (D50)
x=X/(X+Y*Z)=0.3457 and y=Y/(X+Y*Z)=0.3585 in both cases, but the
absolute XYZ values differ (factor 0.89)
Even the xy primaries of both profiles I have are the same as reported by
Photoshop.
Unless of course we're looking at different profiles here....
I don't think so.
... another difference: ProPhoto RGB is a Display Device Profile, (class
"mntr"), ROMM-RGB is a Output Device Profile (class "prtr")
