If you pulled the chromaticity values out of an ICC profile and it is 
a v.4 profile, be aware that those chromaticities are already adapted 
to D50 and the adaptation applied is in the `chad` table. For this 
spec we need the unadapted primaries, as chromatic adaptation to D50 
is already performed in the XYZ to Lab step.
The primaries and transfer function currently in the spec are directly
 from the BT.2020 spec, which is freely available.
