Nobody’s mentioned this but...how about HLG support too? Or will iPlayer content be played in standard HDR?
Also don’t forget YouTube 4K support
All in all great news and I may actually start buying some 4K films!
Youtube4k requires support for the VP9 codec. Probably never happen.
HLG support was shown in the data dump before the ATV4k launched. So it either supports it now or will in the future.
This is again, a different case. In fact, the article repeats, what I have said:
What they do, is a different approach:techxplore.com said:
Do you notice the difference? It is not the earlier discarded info, that is somehow cleverly reconstructed. It is new, different, pixels added. Meaning, the result does not represent what the camera saw. It is a CGI image. The sparrow on the low-res picture has been upgraded with textures of falcon feathers. Result may be perfectly passable for most viewers, but it only proves my single argument - once discarded pixels can not be reconstructed from low-res picture, even algorithmically.techxplore.com said:
PS Also Sony claims to have similar approach in their latest X1 Extreme image processor, where they say having a "dual database processing" with common image patterns that can be used in the upscaling process to improve the result.

I have the 11.2 beta installed and the choices to enable Match HDR and Framerate selected. This does not seem to be working on my LG E6. It is still beta.
Just saw that this will be app dependent. Let's hope all apps get the appropriate update.

What is it not working for you on? I’m aware infuse requires an update and the developers are working on it, but the built in video player, Netflix and plex are all confirmed as working.
For me passthrough audio stopped working on aTV 4K with media players such as Infuse or MrMC. There's only static noise and I know it was working before.
There is nothing stopping YouTube from providing 4k besides themselves. Even if Apple won’t provide native support for decoding, the ATV has the horsepower to decode 4k VP9 in software. infuse pro already supports this on the ATV with 4k content.
Google has already written software the decoder. They just need to incorporate into their build.
No, the lack of YouTube 4k is not a hardware or OS limitation, it is leverage. Google is trying to leverage the popularity of YouTube to convince Apple to add VP9 to their API.
It's probably more than that. There's still no HDR in youtube available even on the Nvidia shield. An android tv platform developed by Google themselves. And that has nothing to do with leverage.
That’s just shifting the goalposts. There are already apps on the Apple TV that can play videos extracted from YouTube in 4k without transcoding.
HDR is a different beast and I don’t know the specifics of why the Shield can’t play it, but the list of supported devices for YouTube HDR is pretty small.
What it's not doing is reverting to SDR where it should. At least not in DTVN. It may switch from HDR 10 to DV but I'm not seeing that yet either. Going to wait and see if apps are updated. The functionality to do it may be there but most likely not implemented across apps just yet.

It's app dependent? Is there a list of apps that work? I'm mostly "worried" about netflix right now. Amazon later.

Recheck tvOS audio settings. They got reset during the last os update and I bet they got reset again.

Netflix definitely works. It should automatically work for apps that use the native video player, though I'm sure there may be some exceptions.
So with the "match source" setting on if I have the TV set to 4K SDR will it automatically turn on HDR when I play HDR content?
The beta is awesome, watching Stranger Things 2 on Netflix and it auto switches to 4k HDR 24p 🙂 I got a Samsung KS8000
It is impressive. Worked for me on 2 out of 3 movies. Lego batman and sing we’re good. Lego movie didn’t switch to hdr.
It’s frustrating because it’s not working for me. It only plays in SDR. My TV is only capable of HDR10 and not Dolby Vision. I wonder if this has something to do with it.
