YouTube HDR content is finally available!
You will find a playlist here. However, these clips will be played as SDR on Sonys for now.
With youtube-dl you can find vp9.2 encodings for those clips:
330 webm 256x144 144p60 156k , vp9.2, 60fps, video only, 2.38MiB 331 webm 426x240 240p60 256k , vp9.2, 60fps, video only, 3.87MiB 332 webm 640x360 360p60 485k , vp9.2, 60fps, video only, 7.35MiB 333 webm 854x480 480p60 909k , vp9.2, 60fps, video only, 13.83MiB 334 webm 1280x720 720p60 1991k , vp9.2, 60fps, video only, 28.18MiB 335 webm 1920x1080 1080p60 3201k , vp9.2, 60fps, video only, 49.70MiB 336 webm 2560x1440 1440p60 11166k , vp9.2, 60fps, video only, 170.23MiB 337 webm 3840x2160 2160p60 20122k , vp9.2, 60fps, video only, 335.45MiB
Those are webm however which the native Video app won't play.
We will see whether we will get support for it soon, even for the early 2016 models with the old MediaTek SoC from last year. At least Sony promised that back at CES:

It usually takes some time to get the bandwidth required for 2160p60 from YouTube servers. My ISP is 120mbps which I indeed get according to speedtest. YouTube nerd stats suggest that bandwidth to their servers is slowly increased to almost 40mbps which is when the app switches to 2160p60. You can also manually switch to the 2160p60 stream.
I never saw the YoutTube app switch automatically to 2160p60hz :(. I always switch it manually... maybe i'm too impatient... And it shouldn't be a case of bandwith as I have 1gps down connection. Maybe the onboard LAN is culprit...
I think the limiting factor is the YouTube servers..
On my own KD55A1 it goes automatically to 2160/60p after some seconds, few frames dropped in between (less than 6) but I can see some micro stuttering sometimes... I am not able to state if it is a problem on the client side, server side or the source video though (I do not have any other device able to g to that resolution). Broadband is FTTC 200mbps (as stated by the router I can go approximately to the speed something like 196mbps, 180mbps using speedtest)
Native YouTube 1.0 was perfectly fine for 2160p60.
YouTube app update from today:
Sounds promising.
Not much of an improvement on my side. User interface is still laggy, especially when playing 2160p60 content. It does ramp up to 2160p60 more rapidly now. Frame dropping/stuttering is still pretty much apparent at that resolution though.
For once I can't really complain. With my XD80, 80 Mbps connection, it seems to go straight to 2160p@60fps (I just tested 3 different videos with Stats for nerds on), and it's surprisingly quite fluid. A frame dropped here and there in the stats, but the microstuttering is at a minimum if not present at all.
Now it moved from a 2160p@60fps video to another and the new one started at full resolution. Zero frame dropped (out of 8500 and counting) in the stats as well.
PS: I see that now in the Stats it shows the colour properties as well. Showing bt2020 (and correctly switching to it. Finally!!).
PPS: Now, after messing with HDMI connections, it's stuttering...

It has been showing that for quite a while already even when the BRAVIA did not switch to it. With latest FW, color and brightness is indeed correct for VP9.2.

Yeah, sometimes it is more, sometimes less. But indeed, the app is now much quicker at switching to full resolution. Also in the nerd stats, bandwidth now goes up to 50mbps rather than 40mbps in previous versions. My ISP is 120mbps and I do get that much when executing fast.com within the Vewd browser, see respective bug-ticket.
VP9.2 is still not functioning properly. It does via YouTube app but when playing such content through other 3rd party apps like Kodi or VLC, the TV does not switch to HDR mode at all.
