But what if I start to tune the gamut emulation with the internal processor of the display hardware? The primaries will virtually change every time I change the hardware settings.
The gamut emulation does not change the native primaries, but the emulated/virtual primaries are constructed by mixing the native primaries. So the spectral basis functions still remain the same, and thus the correction matrix can remain the same too. [ I'm actually more concerned about the deviation of many LCD displays from additive behavior. A 3x3 correction matrix for a non-colorimetric 3-channel sensor is strictly speaking only valid for measuring a set of spectra which can be represented as linear combination of three basis spectra, i.e. the correction matrix for a particular display is only valid for _all_ colors that can be emitted by the display if the display is additive (which is not generally granted). Hopefully the error is low in practice, since this is a source of inaccuracy we have to live with. ] Regards, Gerhard
