Hopefully Microsoft patenting the thing someone else invented (ANS)[2] doesn't gum this all up.

- JyrkiAlakuijala 4y agoJPEG XL in lossy mode models SDR and HDR images using the same model (absolute color XYB). This reduces tweaking and makes it easier technically to create mixed SDR/HDR composites, animations or overlays. All other coding systems that I know of use a different coding method for SDR and HDR, meaning that the quality settings and other encoding parameters are slightly different for these modes.
