Both are HDR formats, but they handle brightness and color information differently.
HDR (high dynamic range) improves contrast and color range over standard video, and Dolby Vision and HDR10 are two different technical standards for delivering it.
The more widely supported format, using a single set of brightness and color settings applied across an entire piece of content.
A more advanced format that can adjust its settings scene by scene, but requires specific licensing and hardware support to work properly.
Your TV and streaming device both need to support whichever format is being used for you to see the intended result — otherwise playback typically falls back to a compatible format automatically. See our 4K and HDR streaming requirements guide for the fuller picture, and check our Devices page to confirm current platform support.
