In case you might find this interesting, with regards to colour matching Sony wrote this very readable 7-page whitepaper on
Colour Matching Between OLED and CRT
It says that an identical colourimetric instrument measurement of colours on CRT and OLED (i.e. theoretically the colour perception should be identical for both devices) still yield a different human perception of the colours on both devices. This because the spectral distribution of the light sources in both devices differ.
Sony argues that for the colours to more accurately match perceptually, an adjustment has to be made on the OLED to the 1931 CIE coordinates of the D65 whitepoint, the so called “Judd-Vos” refinements to the 1931 CIE model.
Sony has implemented this adjustment as a single offset on their pro OLED BVM/PVM monitors (see page 7):
This offset based on the “Judd modified correction colour matching function” will be applied to the following
models effective from 2012 autumn shipping. <…>
Offset Values (from reference white point):
(Δx, Δy) = (-0.006, -0.011)
(x, y) = (0.3067, 0.3180) for D65
From some further reading I understand the Judd-Vos refinement offset is different per display technology (LED, OLED, Plasma) and varies also a bit per model, such that the adjustment is not a specific single value but yields a range. See the document here for information on the adjustment range per technology, mostly page 8-10:
Towards Standardizing a Reference White Chromaticity for High Definition Television
I’m not sure if this “Judd-Vos” adjustment has become industry practice by now for imlementing in hardware, but with the focus of sites like RTINGS.COM etc on measuring exact D65 1931 CIE values, I suspect it is not industry practice to include the adjustment in hardware.
As such maybe it could be considered for the shader. That said, possibly the change is too marginal to really notice unless you’re in a Sony studio looking at their OLED BVM
