YouTube recently began rolling out support for high dynamic range video content on iPhone X, as noted by users on the MacRumors forums and Reddit. HDR videos provide a broader range of colors and luminance compared to sub-HDR content, and the format also supports quality video playback on a wide variety of screen sizes.

For iOS users, YouTube videos in HDR can be viewed on the iPhone X, but the feature does not yet appear to be working on the latest iPad Pro models. YouTube has many HDR-supported videos on its site, with dedicated channels like The HDR Channel providing videos for you to watch in HDR on iOS. To make sure of the quality of playback find a video to play, then tap anywhere on the video itself, tap the three dots in the top right-hand corner of the screen, tap "Quality," and then make sure it reads 1080p60 HDR.

Apple debuted HDR support last year with the "Super Retina" display in the iPhone X, which became the first HDR OLED display incorporated into one of Apple's smartphones. Apple also lists the iPhone 8 and iPhone 8 Plus as supporting HDR, but the displays for these devices are not the same as the Super Retina display on iPhone X, so any HDR content played on the 8 or 8 Plus isn't true HDR.

On the iTunes Movies Store on Apple TV 4K, select films also support 4K, HDR10, and Dolby Vision when paired with compatible 4K television sets. Although YouTube recently updated its Apple TV app and listed a few videos as "4K," the app still has yet to support true 4K. When viewing details about a video, maximum available resolution is still listed as 1920 x 1080, while 4K resolution is 3840 x 2160.

Wow. Watching on my X and HDR is amazing. When watching a non HDR video it looks pale in comparison.

I wonder if there will ever be 4K YouTube on the ATV.

Would this be Apple's fault or YouTube's fault?

Well, I am pretty sure it is YouTube's fault for updating the tvOS app with that horrible UI. My YouTube usage has decreased a lot because of the app.

About time! Only been 3/4 of a year!!

Edit: Wow. It’s like looking through a crystal clear window. I’m actually speechless that this quality is possible on a phone.

1.) Which type of HDR ? PG or HLG ???

2.) Is it using ICtCp ???

Simply saying "HDR" is meaningless !

If it said Rec. 2100-compliant, then that would be best !

MacRumors should be RE-named "MacRumors for Dummies" !

"YouTube recently updated its Apple TV app and listed a few videos as "4K"..."

So, if they say it's supported and they've even listed a few as "4k" but it's NOT... Then what is it? Are these videos any better at all somehow? I'm confused because, while I know that YouTube content isn't actually 4k on the AppleTV 4k, the 4k videos still look amazing. Not as amazing as they do in 4k, but still somehow better than their 1080p counterparts. And I'm just wondering why/how...?

google wants to use their own codec VP9, but apple does not support that codec.

but since VP9 is royalty-free i'd say apple is at fault. you can't expect google to have every video saved in another format just for apple devices...

Yea, this was my thoughts on it too.

The X also has an 8bit color depth display, so not exactly “true” HDR. It has better contrast then the 8 plus, from being OLED.

HDR compatible is more accurate.

While I agree with some of that (not sure about the whole "ruins our lives" part) from the consumer point of view, you can also say that what YouTube used to be like wouldn't survive to this day if it wasn't for things like those ads.

What codec?

Considering that YouTube favors license free VP9 for 8K/4K HDR which Apple doesn't support it's most likely just H264 HDR since it's capped at 1080p.

Wonder what the obstacle is with adopting VP9? Is Apple being cheap saving a few pennies from the extra die space or arrogant? Even the cheap $40 Android TV boxes coming out with Amlogic S905D2 and S905X2 SoCs support H264, H265, VP9 and upcoming open standard AVS2 codec.

If anyone else would like for apple to include the VP9 codec into iOS, please fill out this form. Thanks ;)

https://www.apple.com/feedback/iphone.html

Apple already made the decision to go with HEVC (H.265). This was a deliberate assault on VP9. While Google obviously has a lot of influence, Apple’s decision to go with HEVC definitely dealt a strong blow to VP9.

Much of this is also due to H.265 being ready sooner than VP9.
