		jiggawatts 3 days ago \| parent \| context \| favorite \| on: JPEG XL Test Page Support is not a boolean. A proper test page should have HDR images, images testing if 10-bit gradients are posterised to 8-bit or displayed smoothly, etc... iOS for example can show a JPEG XL image, but can't forward it in iMessage to someone else.

There have been a few other test pages posted in the comments with varying degrees of additional context.

HDR support is an anti-feature. Nobody want a part of a website to suddenly be 10x as bright as pure white.
