User level: Level 1 (5 points)Advertisements in apps change screen brightness. I have my screen brightness set pretty low. While scrolling through Facebook or ESPN apps (among others), some ads will override my screen brightness settings and appear significantly brighter than anything else on screen. It is incredibly obnoxious, and I can’t find any solutions online.

Check the settings in the apps to disable HDR (High Dynamic Range). If it’s enabled, please disable. Do you have Auto Brightness on your iPhone enabled?
iPhone > Settings > Accessibility > Display & Text Size > scroll down > Auto Brightness > enable.
That might adjust for HDR images, but it worth a try too.

iOS does not offer a system wide “play all HDR as SDR” switch for third party in app content, and Facebook does not to provide a reliable iOS setting specifically to suppress HDR rendering in ads.
There are work arounds, but they’ll affect you standard resolution content as well. A simple way to test a potential solution is to reduce the White Point at this path,
iPhone > Settings > Accessibility > Display & Text Size > Reduce White Point > you can also disable Auto Brightness and manually adjust screen brightness. You can even say something like, “Hey Siri, lower screen brightness 25%

These apps do not have those settings.
