Hey Roger! This feels similar to looking at color gamut renderings. In both
cases, while one can come up with a hypothesis, I think it’s important not to
conclude anything by looking at the profile and/or it’s calibration curves. In
order to make statements about final print quality one must make prints with
the profiles and evaluate those prints, both visually and colorimetricially
with measurements. Or in your example of display calibration, one must visually
analyze evaluation images onscreen and take verification measurements with the
final display profile. Again, visual and colorimetric evaluations with the
final profile are essential to making statements / conclusions.
After all, the calibration curves might look incredible and smooth but, in some
situations, the final image quality could still be poor. The two don’t
*necessarily* correlate.
PS: if you want to see more examples and dialog about how color gamut
comparisons can yield false conclusions, check out the "Polarized M3
Observations” section of my i1Pro3+ review.
