What do the macOS and Windows docs say must be configured for HDR video to play as HDR on a given screen?
HDR display state depends on OS settings a page cannot see: macOS needs the external display's HDR setting on and plays HDR as SDR on battery when 'Optimize video streaming' is on; Windows leaves HDR to the user, sets an SDR reference white that apps should match, clips content the display cannot show, and has no single standard tone-mapping algorithm. Reviewers should report these settings with any HDR judgement.
