If I had the book... no, I don't...

Well, HDTVs usually offer 6x3 adjustable contols for gamut calibration:
primaries and secundaries with either Red,Green,Blue or
Huye,Saturation,Luminance values for each of the six directly adjustable

The color calculations usually happen in the YCC color space (no matter what
is the input format), not in the RGB space, so the 3D device gamut could be
anisotropic (non-additive color mixing).

I guess the luminance targets are calculated as to match the primaries with
the white point, so the calibrated primary colors would produce the actual
white point if the color mixing would be additive (it isn't).
