This one packet/frame level only, not global.
It is in sd_global_map
Then that's a mistake, and I'm probably he culprit. HDR10+ is per frame
metadata. Static HDR metadata are mastering_display and ccl.
Is this option meant to also choose which one of those to use?

You can have packet side data at the container level that corresponds to
the same thinga per frame side data at the bitstream level does. In
HDR10+ case, Matroska may have it in block additional, and then afaik it
could be present in the hevc bitstream.
One of them should have priority, or the user could be given the choice.
