Apple TV makes audio sound overly spatial on AirPods, even with Spatial Audio turned off

Spatial Audio seems to remain active on my Apple TV even when it’s turned off. Video audio sounds overly spatial, as if it’s surrounding my head. The same AirPods sound completely normal when watching the same content on my iPhone or laptop. I’ve tried two pairs of AirPods, forced Stereo output, restarted Apple TV, and reinstalled the app, but nothing helped. Has anyone found a fix?
