(Don't take this seriously)
All I did was feed it the color-representation protocol and ask it to write a detailed Wayland protocol for displaying HDR content on a screen. I didn't give it any additional context other than asking it to rewrite everything with more examples and use cases. So this is the second iteration of the protocol it came up with.
Is this super useful? Maybe? I don't know. However, I thought it would be fun to share what it came up with. Have fun reading!

The protocol is intended to be used in conjunction with the Wayland protocol for displaying video. The protocol uses the SMPTE ST 2086 metadata for mastering display color volume, and the HDR10+ static metadata for content encoding. These standards define the necessary metadata for accurately reproducing HDR content on an HDR display. The metadata includes information about the color gamut and luminance range of the display, as well as the color gamut and luminance range of the content. Example use cases for this protocol include displaying HDR video or images on an HDR display, or displaying HDR content from a game engine on an HDR display. </description> <interface name="wp_hdr_manager_v1" version="1"> <description summary="HDR factory"> This global is a wp_hdr_v1 factory.
