Dolby Audio

With the launch of tvOS and the 4th Generation Apple TV (aka Apple TV HD) in 2015, Apple opened up support for Dolby Audio™ and made the Dolby Digital Plus™ format accessible to all tvOS developers, enabling anybody to create a music or video streaming service with high-quality sound or to take advantage of Dolby Audio in local apps and cut scenes for games.

Expanding on this foundation, Apple launched the Apple TV 4K in 2017 with support for revolutionary Dolby Vision HDR and 4K video, giving developers the ability to deliver unparalleled picture quality with vibrant and accurate colors and an incredible dynamic range from true blacks and deep shadow detail to the brightest whites.
