Hi,
Does anyone know the D65 white point for 32EP950 to overcome metameric failure?
Thanks!

We are waiting for one of our manufacturing partners to supply a display with the same screen.
But, JOLEDs suffer very bad metamerism...
It is unlikely the normal approach will work.

To test, I'd initially calibrate as normal, as per usual calibration workflows.
(Using a Spectro to make a probe match.)

Then check the result against a well calibrated 'normal' display.

And when that fails, I'd do a Perceptual Match approach...
(https://www.lightspace.lightillusion.com/perceptual_colour_match.html)
With that, do another visual comparison with the 'normal' display you matched to.

Look especially at 'colour', as the white point should be correct.

You may then want to try perceptually matching Red, Green, and Blue too...
