I'm guessing a percentage indicator is using a calculation based on miles driven. I know that sensors work by wearing down with the pad until a wire is exposed setting off a dash light. But a percentage indicator seems like it's a guestimate. Otherwise, it would need to be continually measuring pad thickness.

I don't think it's going to just be miles driven, the car knows the speed, regen, and when the physical brakes are used too... so it's a little more accurate than that.

You'd hope, but so far I'm not finding any details. I also looked in the 2022 Hummer EV Owners Manual.

Hummer doesn't have brake wear information... Also it's not running Ultifi yet.
