Ah, I think I searched for "jpegxl", that's why there was no match.

#13JPEG-XL provides the best migration path for image conversion from JPEG, with lossless recompression. It also supports arbitrary HDR bit depths (up to 32 bits per channel) unlike AVIF, and generally its HDR support is much better than AVIF. Other operating systems and applications were making strides towards adopting this format, but Google was up till now stubbornly holding the web back in their refusal to support J…
It's not just Google, Mozilla has no desire to introduce a barely supported massive C++ decoder for marginal gains either:

avif is just better for typical web image quality, it produces better looking images and its artifacts aren't as annoying (smoothing instead of blocking and ringing around sharp edges).
You also get it for basically free because it's just an av1 key frame. Every browser needs an av1 decoder already unless it's willing to forego users who would like to be able to watch Netflix and YouTube.

Not anymore. JPEG had the best HDR support with ISO 21496-1 weirdly enough, but AVIF also just recently got that capability with 1.2 ( https://aomedia.org/blog%20posts/Libavif-Improves-Support-fo... ).
The last discussion in libjxl about this was seemingly taking the stance it wasn't necessary since JXL has "native HDR" which completely fails to understand the problem space entirely.

Can AVIF display 10 bit HDR with larger color gamut that any modern phone nowadays is capable of capturing?

Wanted to note https://issues.chromium.org/issues/40141863 on making the lossless JPEG recompression a Content-Encoding, which provides a way that, say, a CDN could deploy it in a way that's fully transparent to end users (if the user clicks Save it would save a .jpg).
(And: this is great! I think JPEG XL has chance of being adopted with the recompression "bridge" and fast decoding options, and things like progressive decoding for its VarDCT mode are practical advantages too.)

Typical web image quality is like it is partly because of lack of support. It’s literally more difficult to show a static HDR photo than a whole video!

Not everything in the world is passive end-of-the-line presentation. JPEG-XL is the only one that tries to be a general-purpose image format.

Is it just me -- or it's confusing to use the terms issue / bug / feature interchangeably?
