To stop this discussion, If I calibrate a display, projector or TV, or screening monitor, I deliver a report,
end of that story. If I forget that,,, "I never do", I can easily look up the calibration by date and name and make a pdf and send it by mail to my customer instantly. This is just something you do. All professional calibrators I know give a calibration report to the customer. SDR, HDR, Dolby Vission.
The calibration report is the only value paper a pro calibrator can give a customer. Also to show before and after work is done. Even before I started professionally with calibration I got reports on my projectors.

@Stridsvognen You say:
"For HT projectors ill think they come in the following order when comes to HDR capabilities."
1 JVC 25000:1 native panel on off contrast
2 SONY 8000:1
3 EPSON 4000:1
4 DLP 1000:1
HDR is "HIGH DYNAMIC RANGE" for shore and 1000:1 up to 10000:1 will not be a kickass for that. Your numbers are quite correct native full pop.
HDR on projectors today is more "the tone mapping" and therefore looks good on low contrast projectors too. But side by side with a high contrast projector correct tone-mapped HDR big difference trust me.
