Spatial Audio on Beats Studio Buds+

Control Center has incomplete controls for my new Beats Studio Buds+. The one for noise cancellation is present, but the one for Spatial Audio is missing.

By sheer luck, I eventually found the setup for Spatial Audio Personalization via ear scans in the Sounds & Haptics section of Settings. But setting that up still did not cause the Spatial Audio control to appear next to the Noise Cancellation control under the volume slider.

My iPhone is running 16.5.1. Is there anything else I can try to make the missing control appear?
