In the industry people just call it the DCI P3 white point (or 'Urgh')
it is not limited to theater usage, you might consider it the
calibration white point for the reference projector, so
WP_DCI_P3_REFERENCE might be better, but that is a little long.

I'd go for something like WP_DCI_P3 it is not really ambiguous.
