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:
YouTube will also start streaming in HDR quality later this year, using a new VP9-Profile 2 codec that brings HDR support to Google’s VP9 video format. Sony’s Motoi Kawamura, Head of TV Product Planning for Sony Europe, confirmed to FlatpanelsHD that the 2016 models will support VP9-Profile 2 and be capable of streaming YouTube in HDR. We saw a demo at CES and it looked very good.
In my TV it still stutters much less frequently than the awful Amazon Video (which doesn't go above 30 fps) and now even Kodi. The app is fine, it's the CPU/OS couple in the television that's awful.
Tried FW 3.925 on my ATV1 based TV which claims to improve YouTube 4K...
Resolves YouTube 4K playback issue (2560 x 1440 resolution or higher)
Dunno which problem it solves, but it is not the micro-judder issue discussed in this thread. YouTube 2.0 CPU usage is still high, micro-juddering is still there for 1440p60 or 2160p60.
Same on Android 7.0. It fixes nothing. The most it's doing is that now most of the 2160p@60fps videos I checked play at 1440p@60fps. And still with frame rate drops.
Not even the volume bar has been improved!! Most useless update ever until now. After 6 months I expected a fully working OS!
What do the nerd stats say about 'Connection Speed'?
It depends. from 18 to 35-40Mbps at 1440p@60fps. I tried the usual "The World in HDR" the last time and it went up to 2160p@60fps after more than a minute. Personally I don't see any improvement.
And no, HDR with vp9.2 is still not supported!! This update is a complete disappointment. Six months waiting for nothing. Apparently Sony is more interested on supporting Alexa and that useless Samba TV (which kept crashing every 10 seconds because I had it disabled) than on fixing this OS.
So, the YouTube app has been updated, it claims it improves performances, but the only differences I see are the new (white. Urgh!) icon and the new animated splash gray screen.
In terms of performances just after the update it was stuttering playing 2160p@60fps videos. Then it has got smoother, just microstuttering as usual. I am starting to wonder if the vp9 codecs aren't broken, or worse, the ASIC doesn't fully support it at max performances.
It is a huge mistake what they did. A wrapper with this "web lean back launcher" running on top. It's just bad and will stutter. It does even on shield. Bad.

You can download 2160p60 VP9 webm from YouTube and play it inside Kodi. I fetched quite some samples with Opus and Vorbis audio which play perfectly smooth at much lower CPU usage compared to the YouTube app. Kodi plays them from a fast NFS share though. Bandwidth is not the problem though.

Oh yeah, I didn't think about that. I think in the past I only downloaded few HDR videos at 30fps to test the HDR. I'll give it a try.
It's true that YouTube at 2160p@60 still uses an awful lot of CPU (I get 20% idle max).
