I find it especially curious that they got 95% sRGB coverage in the emulation mode on their screen, and such bad gamma. Also a huge dip in top left corner evenness. Smells lemony.
In fact someone on their forums had a different lemon problem with different issues, backlight instability etc. Replacements tended to work, Asus and sellers tend to be nice about returns on this high end hardware.
Coverage at native gamut (intersection with X colorspace) is fixed by physics.
OTOH in “gamut emulation” (non native, emulated) coverage small% variances usually points to:
-slightly wrong matrix for emulation (non matching simulated primaries vs target), “software” issue
-slightly non ideal “volume” because matrix gamut emulation is not enough (panel) or if LUT3D small number of patches fro making it (“software” issue + poor QC)Given 3dC uniformity errors even with uniformity compensation active, all points to non existent QC in Asus HW + additional poor QC in factory calibration. At least a colorimeter like a i1d3 is mandatory with these screens, a minimum requirement.

I suspect Asus allows a slop here because they do sell PA32UCX-K coming with i1d3.
