Comment (by Balling):

 DCI-P3-D65 from https://www.color.org/chardata/rgb/DCIP3.xalter is 2.6
 gamma. Did you even look into rTRC of it? It is not really relevant, is
 it... Its Red Z is -0.00081, so negative, so noncompliant. **Why would you
 think ICC pages will have no bugs? LOL.

 >Except that the media white point in the ICC profile is correct (D50),
 whereas the one in the Apple profile is incorrect (D65).

 So? I told you that. Who cares. It is not used for color managment. ICCV4
 is always USING D50.

 >instead of the (correct) "Inverse(chromaticAdaptationTag) *
 mediaWhitePointTag

 No. ICCV4 is always USING D50. WHAT?? You do not need this and even chad
 is not used really, except to make negative Z of R positive.
