Colorimetry is, or should be, part of the track meta data, where it can be 
accessed regardless of rendering mechanism, regardless of track selection, and 
can be extended without breaking apps.

The video output already is supposed to have the shaders for colours inside 
OGL / DX outputs. I don't see why the rendering callbacks should care. 
Besides, that will break as soon as a new enum member needs to be added, and 
the app does not know it.
