I will say windows implementation of HDR - at least the way Chrome handles it within Windows is somewhat of an abomination - so I'm sure Apple's iOS is just as poor!

but sometimes it's not HDRs fault - it's just the segura effect. People with cameras exceeding their capability levels, not understanding what you need to do after you shoot video in LOG.

I mix multi-monitor some-HDR some-SDR in Windows, it's bad.

Nah iOS really cranks up the screen brightness to display HDR content.
