Hey devs! Heads up, we're planning on making some changes to our image CDN tomorrow. - Images will be served as WebP by default - The URL format you get from the Bluesky API will change a little You can look forward to an announcement about image quality soon 👀

If Bluesky wants to support #HDR images, as produced by many modern smart phones, webp is not capable. Ultra JPG (jpg + gainmap), AVIF (high bitdepth or gainmap, second broadest browser support after UltraJPG) or JPEG XL all do support HDR.

As is your right. :) That being said, webp will discard user data by throwing out the higher bitdepth information they upload to Bluesky, whereas the other formats will not. Those users will only notice that their photos look washed-out and dark on Bluesky, whereas they look fine on other platforms.
