jpeg xl does support lossless and their 69 page paper does mention this so I am unsure why they are putting the lossy aspect of this as the comparison to their “lossless ZIP COMPRESSION of OpenEXR”
page 51 has more detail on compression stuff. The openEXR does also support lossy. Anyway I think page 51-52 would answer it for someone that knows more about openEXR which I sure don’t
Their comparison images do clearly show data being lost as well so they aren’t even using visually lossless of jpeg xl they are actually just going full lossy. Must be some use case somewhere?
