HDR10+ uses dynamic metadata like Dolby Vision will we see it in projectors?

Since 10+ uses dynamic metadata like Dolby Vision will we see ever see it in projectors?

Hence, no projector makers have released one with Dolby Vision.

Dolby Cinemas use Dolby Vision because they use specific equipment and control ambient-light to the point that they know how to calibrate it so that the light from the screen reaches a specific level which Dolby Vision can use to properly render the picture through the projector. Since at home equipment and ambient light varies so much from setup to setup, there’s no current way for companies to include it and make sure that it works as intended. For flat screens it’s a different story because their brightness levels are known and they don’t noticeably degrade until thousands upon thousands of hours later, and ambient light affects their performance way less compared to projector setups. I think it will come to projectors at some point but not anytime too soon.

P.S: The best HDR projectors currently available come from Sony and JVC. They have the best tone mapping currently available for HDR content. If you can control ambient light and have a pitch black room, I would recommend a JVC projector as it has the best native contrast for a projector, which HDR relies a lot upon. If you go for the mid or higher end pro series you’ll also get a wide color gamut as well that pretty much matches the colors that most projector cinemas have.

The only reason I have heard of as to why Dolby Vision isn't allowed on consumer projectors is Dolby has very specific standards that that they want to meet so Dolby holds their cards close to the chest.

I am assuming that future projectors will be able to do HDR 10+.

I can't say for sure, but I'd wager "no".

DV adjusts based on the display's capabilities. Too many variables with projector setups at home means that DV isn't certifiable for home use.
A movie theater can have DV, because it is a controlled environment, with specific projectors, and a known screen size for that room. Thus, DV can be calibrated to match those specifications.

However, at home, you can have a totally dark room with white walls, or dark room with black walls; lights on at any point; more lumens required at 150" versus at 50"; .8 gain screen or a 1.5 gain screen; black diamond screen, white, grey, or HC grey screen, so on and so on... DV won't look the same if any of these conditions are changed, thus, no DV for home projectors.
That's how I understand it.
