I don't know if we've ever explicitly discussed this, but if the Studio config intends to provide implementations of all the color spaces described by the current CIF Color Space Encodings for Displays guidelines, we should add g22_adobergb_display, g26_xyzd65_display, and pq_xyzd65_display display color spaces.
(I feel like we've discussed and dismissed the idea of adding DCDM Displays, but I'm not sure if we dismissed adding display color spaces, per se, or whether those discussions took place before the CIF guidelines were authored)
