That’s what Apple states, yes, but I suspect that it’s also used for calibrating the inner microphones of newer AirPods which is used for the “live eq” which works by listening the feedback inside the ear.
From my experience, Apple can sometimes “forget” to tell things.
Modern Apple gives you control over everything by hiding it in Accessibility settings. You can control almost everything about AirPods and give them custom EQ there. But it doesn't have that.

Adaptive EQ? Apple says otherwise [0].
What I was talking about was the "realtime" adaptive EQ tuned by pods' inward facing microphones.
What I argued was, this adaptive EQ also uses the calibration data from personalized spatial audio data.
That's only for spatial audio.
