A few streaming services have supported colorful high dynamic range video and ultra-high resolutions for a while, but Vimeo is making up for lost time in grand style. The company has added support for both HDR videos and resolutions as high as 8K. You're going to need a very rare 8K display to see footage in its full glory. However, HDR support is considerably broader: you 'only' need a device that can play HEVC video using HDR10. Some of Apple's newer devices (including the Apple TV 4K, iPhone X and 2017 iPad Pros) already do, and Vimeo is quick to point out that it's currently the only video hosting service to play HDR on Apple gear.
