Issues Detecting Apple TV's HDR Playback Capability

I've been working with the eligibleforhdrplayback property to determine if HDR playback is supported. However, I've noticed an inconsistency. When the video format switches from HDR to SDR in settings menu on Apple TV, the property still returns true, indicating HDR is playable even when it's not (This seems to contradict what was mentioned around the [20:40] mark of this WWDC video).

I've tried using the eligibleForHDRPlaybackDidChangeNotification and even restarted the app, but I still encounter the same issue.

Are there alternative approaches to accurately determine if the app can play HDR content on Apple TV?
