4K YouTube works "fine" here with my 25mbps connection. But it depends. I can obviously not play 4K clips with 30mbps, like The World in HDR. The YouTube player however goes up to 2160p60 for lower bitrate content like this one (~15mbps). However the new player consumes lots of CPU time, introducing lots of judder when playing high frame rate video. Old YouTube 1.X app used to consume a fraction and 60p was perfectly smooth. So YouTube 2.X on Android TV is for sure not where it should be.
The 4K issue you are experiencing might not be due to Sony but limited bandwidth on Google servers. Sometimes network bandwdith on the TV is dramatically reduced too. It might help to reboot your TV (long power button press or power cycling).
As for YouTube HDR, Sony promised support at CES2016. Sony/MediaTek are always 1 year behind. So I am confident that an update will arrive eventually, only for TVs based on the ATV2 platform though.
