# Steps to reproduce 1. Load https://hsivonen.com/test/moz/hdr.html in Firefox and Safari with an SDR sRGB screen. # Actual results The top left image (Rec. 2100 PQ with BT.2408 reference white JPEG XL) looks like the image on bottom right in Safari, but in Firefox the top left image looks desaturated (grayish). # Expected result Expect the top left image to look as good in Firefox as it does in Safari. # Additional info This is not about asking for HDR presentation but about doing good-looking tone mapping when the presentation isn't actually HDR, so that Web developers don't start withholding HDR images from browsers presenting Firefox's UA string.
