Outside of uniformity (I don't know what the spec is, or what being outside it would look like) but I would be quite surprised if a JVC can't easily meet/exceed everything else. With the JVC autocal software, it's quite easy to get a JVC calibrated (SDR) to within 2dE across a 33 point gamma, white point, primaries, etc. As far as uniformity, outside of bright corners (I'll leave that debate elsewhere) there are no uniformity issues that are noticeable even with test patterns.
I'd say a JVC (RS5x0 or above) could even meet it applied to DCI P3, they generally hit about 98-99% of P3.
When according to Cine4home some having bright corners, some vary by 290K across the screen and some having a green primary so far off the standards they cannot be calibrated.
I'd consider any projector like that broken, and seek an immediate replacement, that sounds like an anomaly.
This doesn't apply just to JVC, any of the "high end" projectors (Sony, Epson, even 1080p DLPs) should be the same.
What I know is, I haven't left a commercial theater in years not feeling disappointed, most notably with contrast/black level. The RS600 throws an image a commercial theater (other than possibly Dolby Cinema, which I haven't seen) can't even touch. Same with sound, commercial theaters are pumping out harsh, bloated, distorted, nearly painful audio where as my HT produces deep, full, clear, non-fatiguing sound. Especially now with UHD and WCG at home, I can't think of a single image or sound quality metric that I find better at a commercial theater.
