NEC for SpectraView has this: https://www.nec-display-solutions.com/p/sv/en/technology.xhtml Then an actual factory calibration and verification report in the box for the shipped unit. For my PA271Q, it shows the measured area, the device used and Screen Uniformity in dE (formula not specified) and mine was “Limit less than 3.0). Andrew Rodney http://www.digitaldog.net/

Here's a manufacturer that's willing to post uniformity information on their product web page: https://displaysolutions.samsung.com/monitor/detail/822/U32D970Q I have not read through the rest of the specs but I like these two sentences:
Every UD970 is individually calibrated for uniformity correction by splitting the display into 25 sections, and then adjusting the brightness of individual sections uniformly with the calibrator. This results in center and peripheral areas that maintain an amazing calibration accuracy of △E<3. Less than 3 DeltaE? Really? That's not a bad performance.
