Comment (by Balling):
Funny disscussion, but seriously with HDR one should not copy the metadata
by default. IMO, in so many cases convertation of HDR includes color
management, transfer characteristics changes, luminance convertation and
tone mapping is done by default to just present it (differently according
by device capabilities), there is global metadata and metadata in SEI,
etc, etc. Just read this https://github.com/sekrit-twc/zimg/issues/69 for
new ICtPCp color space which is now part of HEVC standards and new
BT.2100. Crasy one. In so many case the metadata is broken, so you know.
