Fredrick Odhiambo from Intel has asked if we support HDR JXLs, as libjxl itself can't convert them to another format.
Wolthera had already commented that we should add this in the future, and it seems the time has arrived...

> but basically, my approach with this has been to convert to linear upon import, as icc profiles don't support eotf-2084/PQ (or HLG for that matter), and I'd prefer to be honest with the user about that. Then for export I offer the option to convert to PQ or HLG.

Marking as duplicate because (to the best of my understanding) we use libjxl's ICC support for this. It's broken for other reasons that will be addressed in the original bug.
