Does Dolby Vision get converted to HDR on non-DV television?

[Vacendak]

TL; DR: You will have to try it yourself. Best case scenario, everything plays in HDR, because Profile 5 is tonemapped in hardware by the Apple TV, and Profile 8 contains HDR!

Thanks for the helpful information! I did not realize it was this convoluted. If for whatever reason a media file does not play back correctly (color-wise), it will looking greenish or purplish, correct?

Yes, thats right, for Profile 5, there it's really obvious when it does not play correctly, it's unwatchable. The other Profiles should play eighter in HDR or (worst case) in non-tonemapped SDR, which isnt great (low saturation, not much contrast), but it's at least watchable.

If you want to test it yourself, here you can find DV5 and DV8.1 Testfiles, directly from the horses mouth

In general, MediaInfo is the Standard-Tool for something like that, there you can see, what DV Profile a file uses, if it has a compatibility layer and so on.

If you test this, please, report your findings, there are a lot of other people with a similar configuration (non-DV-HDR TV and a Player with "unknown" capabilities) :-)
