A workaround is to check the audio output device. But this has some caveats like you won't see CarPlay, when the user has AirPods active. You can't enumerate available devices (at least I haven't seen the API yet). But you can get the currently active output without any additional entitlement.

Yeah, that's likely the only option, as isDynamicIslandLimitedInWidth was only added in iOS 27 and I'd like to stay with a lower compatibility for the moment. I thought, maybe I'm missing some indicator which I could use. I'll revisit this in a year then :D Thank you.
