Interesting how the images pop on that site, everything else has like lower opacity/faded, worked great, maybe more noticable on retina monitors
macOS puts a slightly higher brightness than it required and artificially (in software) changes absolute white (0xFFFFFF) to greyish color (0xEEEEEE). So when a HDR content is required it will remove mask around that content. Safari ideally, probably that’s on Firefox why tone mapping doesn’t work well
The video looks the same in both Safari and Firefox, whereas the images are dim in Firefox on both my MBP display and external monitor.
