Comment (by Balling):

 >Apple use for all its DCI-P3 content

 No, P3-D65 with sRGB transfer, together called Display P3.

 >The matrix coefficients appear to contain the "correct" values, which is
 ofc wrong as they're *supposed* to be adapted to D50 by spec

 No, they are adapted. Except for white point, which is wrongly not
 adapted. Z for red being negative shows it is adapted.
