It’s bad because it dims the entire display. You’re assuming your app is more important than whatever else might be displayed. It can also take a bit for the os to go back to the sdr state. I’ve had a few cases where safari gets stuck in hdr mode and won’t revert u til I force closed.

I saw a restaurant on Uber Eats with a HDR enhanced image. The whole screen felt dim but I thought it was just me. How can it dim the whole screen?

  I’d assume it’s the display manager dimming sdr content to have sufficient brightness range for hdr content.

> It’s bad because it dims the entire display. You’re assuming your app is more important than whatever else might be displayed. What are you talking about? I have a HDR display, in Chrome on Arch the literal only change in the submission's demo is the brightness of that particular element, doesn't change anything else on the screen, sounds like you have a broken HDR implementation.

  I think they meant that by making an element brighter than the rest you basically change the contrast and the rest will feel dimmer

    On mac the OS remaps the brightness range when HDR content appears. The rest of the content literally and materially dims.

      Lol, so one HDR element on a website changes the entire desktop environment to be dimmer? :P Fun implementation.

  If your setup runs everything in forced hdr you won’t notice. OSes like MacOS will map sdr making everything look dim that’s not hdr.

Dimming the entire display is not how HDR works especially on OLED phone displays. If you are not outside in bright sunlight it’s almost certain that your screen is not at its highest brightness in the first place. All HDR is doing is adding more range between the darkest element and the brightest element. I.e., if you go to this webpage and set your screen brightness to maximum, the HDR effect visibly goes away because you’re already telling your screen to maximize brightness everywhere. Put the screen brightness at 50% and the HDR effect is visible: the bright parts are brighter.

  Just tested it, everything but the bright dimmed. That’s very annoying. On an iPhone 14 Pro…
