The latest update for the YouTube app on iOS now lets iPhone Xs and Xs Max users watch videos in HDR. Last year’s iPhone X had this feature already, but it seems an update was needed for the new iPhones. The downside is videos are still capped at 1080p, which means still no 2K or 4K viewing for you. This restriction isn’t just for the phones, but it also applies to the iPad, Apple TV, and Mac, if you use Safari. But it’s still great experience to watch Full HD videos in HDR and at least now you can enjoy that on those new edge-to-edge Super Retina displays.
