YouTube for iOS gets HDR support for iPhone XS and XS Max, but still lacks 4K

The YouTube app for iOS has received an update that supports video with a high dynamic range the iPhone XS and iPhone XS Max, but it also lacks an opti to watch video with 4K resoluti.

The update to versi 13.37 of the iOS YouTube app adds new optis to the video quality settings, with compatible clips that now show the letters "HDR" next to the resoluti to indicate the ctents of the high dynamic range. HDR optis can be manually selected, but the Auto Quality opti also enables HDR if it is available for the currently viewed video.

HDR allows a wider range of colors in a video to be displayed a compatible screen, as is the case for the Apple TV 4K and a supported 4K TV with HDR support. The effect can provide a brighter, more detailed and vivid image, with fewer color strips and other digital approximati artifacts.

The OLED screens used in the iPhone XS and XR offer high ctrast ratio, making it suitable for displaying HDR ctent, both made by the built-in cameras and those downloaded or streamed to the device via line services.

The additi of HDR to the app has not been announced by YouTube. The release notes for the app versi simply state that it ctains bug fixes and has improved its performance without mentiing additial device support for HDR.

Although HDR support is likely to be acclaimed by users, the app will ctinue to avoid providing optis with higher resoluti than 1080p, with 4K ctent displayed an encrypted resoluti the iPhones. The problem is not ly limited to iPhones, because iPads with higher resoluti screens and the Apple TV can not play 4K 4K or higher than 1080p ctent.

The problem is also clear macOS, while Chrome can offer YouTube video with resoluti up to 4K, but Safari is up to just 1080p.

The problem is probably due to the lack of OS level support for Google's VP9 codec, used by YouTube. Although it is still unclear when Apple will include the VP9 support in its software and devices, it is also unknown whether Google will use Apple's decisi not to use the codec in the software, as with the Xbox e. 4K or 1440p video streams hardware that it could play.
