Comment (by Cosmin Stejerean):

 The ICC profile reading/writing is already behind a flag so I think it's
 low risk to update this to be more compatible with things that we are
 likely to find in the wild (and this Apple P3 profile seems quite common).
 It sounds like ICCv4 not using D50 is a bug, and it seems like it could be
 a safe fallback to assume D50 when reading ICCv4 (ignore the whitepoint if
 it's not D50 in v4 as not being spec compliant).
