Hi Roger,
I have seen measurements of uniformity in done in a variety of ways on
different reports. Below are the factory reports of two BenQ monitors:
https://reflight-my.sharepoint.com/:i:/g/personal/rtelhan_reflight_onmicrosoft_com/EZmTdVPTlvpPh7y-OklIg6sBcAkY_u1TN6hjkbT55SX5Ig?e=qHcMOh

The ASUS report is not specifiying the type of the uniformity measure.
BabelColor’s ISO 3664 Test Report for Color Monitor reports a “Tone Uniformity”
calculated as the percentage deviation from the center point’s Gray/White ratio.
This is all too confusing. Another source of confusion is the reliability of
these reports. I have tried to replicate at least some of the mesurements in
the above reports. They were off the target considerably.
These reports should be more specific about what they measuring.
Best,
Refik

The world of high end monitors is changing?
I stumbled on this "Color Calibration Report" from some Taiwanese
manufacturer:

I'm shocked by the data shown in Page 2, especially the brightness
uniformity; it's all "0.000", at every 25 positions? And the Color
Uniformity barely crosses over the 1 DeltaE mark. Are today's monitors that
good? For a relatively low price, I mean, under $1,000 USD, compared to the
more "respected brands"?
