Are there any HDR 4K movies? How to tell if it is?

Hello, I'm trying to understand all this stuff new HDR stuff. How do you know movie(s) are HDR when you see the torrent page.? 

10bit means it is or isn't necessarily HDR? or 

When you see BT.709 it's not HDR?

So far searching for "4K HDR" gives no results.

Short Answer = You can't, which doesn't matter because it doesn't mean any one definitive thing anyway. Forget about it for a year or two.

Currently, manufacturers are squabbling over the next generation standard to add clauses and specifications to it that they have patents over and to form alliances to trademark terms to block other manufacturers. This is a decent write up: https://www.techradar.com/news/television...se-1322815

Great answer. That is exactly what I have been thinking also. I was hoping to find some torrents so I could see how my Hisense $399 HDR works.
