Hopefully Apple either improves that or changes tvOS so that it requests and plays back native HDR10 versions (rather than DV versions that must be converted) from apps such as Netflix, if HDR10 is available.
Me too. I don't have a DV television, so I'm working with just HDR10. I did some reviews of ATV HDR10 vs Roku Stick+ vs. my Sony tv internal app. In my opinion, the ATV HDR10 content from Netflix or Amazon looks noticeably less robust than on my Roku or TV (which looked very similar).
Now, I'm hesitant to say "worse", because I don't know if it's technically more or less proper. I'm not a torch mode viewer in general, and I always reset my setting down to proper videophile-advised dark room settings, and I watch in dark rooms, but when I watch HDR content I want to see the highlights shine. I don't have a particularly bright TV, but I like to see things like flashlights, car headlights and light coming into a dark room through a window, etc really pop. And of course I like the colors to shine. If someone wants to tell me that this extra contrast isn't really the best HDR, and Apple's is some kind of higher fidelity even if it's less dramatic, I'm not going to fight about it. But to me, that's HDR, bright highlights against dark blacks. And the Apple TV doesn't do it that as well as my other devices.
On the contrary, I actually really like what the ATV does with it's "fake HDR" on SDR content. I definitely don't see it as darker (at least to my taste), and I think it definitely brings it much closer to HDR content. I can't think of anything where I've felt it was distorted. For my money, it does a great job. I watched Future Man on Hulu and it did wonders, it was "more HDR" than some of Netflix's lesser HDR efforts like Death Note and The OA. Still not up to the better implementations of HDR for sure, and some SDR content seems to "convert" more dramatically, but a marked improvement over straight SDR to me.
So I'm in a situation where I watch the ATV for almost everything, EXCEPT HDR programming, which I switch to the Roku or internal TV app. ATV's HDR isn't terrible or anything, but I would love to see them equal what I'm seeing on those apps, especially since Atmos is coming along and it's almost a single-box solution for me otherwise.
