It will be especially important for JPEG XL (JXL) support to also properly handle HDR (10 and 12-bit) images. Legacy file formats are not suitable for HDR. AVIF is likely to have a head start, but JXL is a critical file format to support for HDR given faster encoding and smaller files.

The majority of Apple displays in the past several years have HDR display hardware (https://support.apple.com/en-us/HT210980). This is collectively hundreds of millions of devices now, and the XDR displays (new MacBook Pros, iPhones, etc) are absolutely incredible. However, the only way to view HDR images on the web on these gorgeous screens is with Chrome on MacOS. Safari and WebKit do not support, which means that none of the iOS mobile devices have any support (including via Chrome on iOS given WebKit dependency).
