Yes? Only LMS <-> L'M'S' changes depending on the transfer function. H.273 still defines a single ICtCp matrix coefficients value for both BT.2100 and compositor knows when the picture is PQ or HLG. The matrix coefficient is shared for L′M′S′ <-> ICtCp. |
The matrix coeff. is shred for linear RGB <-> linear LMS, it is not shared between L′M′S′ <-> ICtCp... I' is derived the same though. |
