1. A computer-implemented method comprising:
performing analysis to determine information associated with a high dynamic range (HDR) media content item;
deriving a standard dynamic range (SDR) version of the HDR media content item using HDR metadata, the deriving including encoding the HDR media content item to SDR content and normalizing data of the SDR content;
transmitting the HDR metadata and the SDR version of the HDR media content item with embedding of the HDR metadata within a protocol with the SDR version to a storage service; and
causing the HDR metadata and the SDR version to be received at a display device, wherein the SDR version is converted to HDR per incremental portion with a dynamic range bounded based on the HDR metadata of the protocol.
