Would be nice to have user-space uAPI docs for the colorop properties. Just like we have for other KMS object types: https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#standard-connector-properties
Internal kernel docs aren't great for user-space developers, because user-space developers have no clue where to search the docs. I think it's totally fine to refer to the uAPI docs from the internal docs, though.
