Right, but these new devices, being colorimeters, can't get the 'spectral response of any display'... you'd need a spectrophotometer for that. So I don't know how they can claim that these would work with any display in the future. If that's what they're claiming.
To get an accurate result using a ccmx you need at least the spectrometer, the colorimeter and the display, and you get an accurate correction for just that serial number colorimeter. You may get a ccmx that will improve other colorimeters of the same type, but it won't be as accurate. With the scheme above, all you need is for someone with a spectrometer to measure the display, and then everyone else with any colorimeter that uses this scheme can use the measurement to create a n accurate correction matrix for their particular colorimeter. That reduces the scope of the problem considerably. Graeme Gill.
