Like most OLEDs, QD-OLEDs like the Asus PA32UCDM also suffers from colour metamamerism, displaying too green.

Those of you who use an alternate whitepoint, which values have you arrived at? Did you use a CRT as reference or some newer display technology?

I used an normal srgb laptop led lcd screen as reference.

Although maybe a CCFL lcd is a better choice

I'm still a beginner trying to understand the science behind all this, so please forgive any misunderstandings. From what I gather about metamerism in monitor calibration: two displays can show the exact same RGB values but still look different, because their backlights or primaries emit different spectra.

What I don't fully understand is — how do you decide which display is the reference? Why choose an LED or CRT as the standard instead of an OLED? The white point on an OLED might look different from an older display, but does that actually mean it's worse?

I'm working with a single monitor setup, so metamerism might not really apply to me unless you're saying that the white point on OLEDs is inherently inaccurate and should be visually corrected using another display technology that renders white more 'correctly'. Is that the case? Assuming that reference display's whitepoint is correctly calibrated.

The wider the display's gamut is, the "spikier" or narrower the primaries are, making it more susceptible to metamerism. CRT and CCFL LCD have smaller gamuts and wider, less spiky primaries. They are also usually within the capabilities of consumer meters to measure and adjust to D65 before using them as a reference to visually match something like an OLED to.
