--- Comment #2 from Adam Argyle <argyle at google.com> ---
I came here to report that Safari on Desktop properly reports HDR CSS color support via `window.matchMedia('(dynamic-range: high)').matches` but iOS Safari on iPad Air 16.4 and iPhone 14 16.4 do not. They return false, as if they're not a HDR capable display or browser instance, when i can in fact see p3 color support.

This has the effect that when visiting a site I'm making, Safari on iOS is getting SDR colors instead of HDR.
