--- Comment #13 from Greg <greg323464 at gmail.com> ---
Here's a test page with images encoded with ACR v15.1: https://gregbenzphotography.com/hdr-gallery/

If viewed on an HDR monitor, the page will render HDR AVIF images (if viewed on an SDR monitor, it will serve SDR JPG, but you can click the green button towards the bottom left to force it to render the HDR AVIF). These images include new metadata that help further improve rendering of HDR images. When viewed with the latest Chrome Dev or Chrome Canary, they show a notable improvement even over rendering in browser like Chrome that already supports HDR. This is a separate issue tracked in https://bugzilla.mozilla.org/show_bug.cgi?id=1805436.
