Description Greg 2023-12-04 09:08:23 PST 
HDR AVIF photos are tone mapped to SDR even on HDR / XDR displays, when they should be displayed with proper HDR (EDR) results.

The Chrome, Edge, Brave, and Opera web browsers all properly display such images. While all of those browsers are a suitable workaround on MacOS (instead of Safari), they are all dependent upon WebKit for browsing on iOS / iPadOS. Therefore, it is not possible to properly view HDR photos on Apple iPhone / iPad, which is unfortunate as Apple has some of the best hardware out there.
