Dolby Vision profiles and levels define various degrees of HDR performance and capabilities.

Profiles represent different use cases, such as compatibility with SDR displays or delivering the highest-quality HDR performance.

Within each profile, levels specify the visual quality, enabling content creators to tailor experiences for diverse devices and viewing environments.

Together, profiles and levels ensure optimal playback and compatibility across a wide range of devices and scenarios.
