I hope so, but I disagree with the size of the "except": JXL performs better than APNG and GIF, and still supports transparency and lossless encode. Video codecs struggle here. So even with animation it still depends!

There's also a case for AVIF in some use cases (for this image it performs poorly). But if I had to choose one, I'd choose JXL.

Gnome ships wallpapers in JPEG XL. Decoding support has landed but export support is either sparse or untuned.
