Safari/or youtube ios app doesn't support more than 1080p, no matter if you are on safari 4k/5k imac/mac or ios device

Looks fantastic indeed, I just wish the Tech YouTubers i follow shout their stuff in HDR, I’m MKBHD will start doing this though, he’s videos are very crispy.
 
This might be an obvious question, and I think I might be missing something here, but when playing the video above, the app says it’s playing in HDR, but should I put the brightness to maximum to get the true HDR affect or is it all automatic? Thanks.
