xperia xzp 4k hdr playback

[SATZDAS]

Is there anyway to know if I am playing 4k hdr video in default app.In youtube it supports only 1080p hdr with horrible framedrops.I have tried some 4k hdr mp4 samples but it seems that its only playing it in 4k because in youtube when I select hdr, the app takes over the brightness.Has anybody played downloaded 4k hdr video yet.Let's have a discussion below

same here, 4k hdr doesnt appear in youtube only 1080p hdr, frame drops could be due to "debug gpu overdraw" option enabled turn it off in developer options i think it should do it...
how did you manage to download 4k hdr video? I tried every youtube downloader I cant seem to download with that option...

Try 4kmedia.org and you can download full 4k hdr videos sample.My Developer mode is off.There is obvious frame drops and battery drain while playing HDR.Sony is bullshitting with us.If you find a way to play 4k hdr video let me know
