Apologies for lack of a better source. A slide during the live presentation mentioned this. I’d estimate a 10% chance I’m misremembering.

Pretty big slide at 0:29:28 into the event:

That said, this was talking about the Apple Watch Ultra. I'd assume it's the same for the phone, but I don't have proof of that.

Thanks! Indeed, it seems logical that they’re shipping the same tech inside these same gen devices. I think Apple has been very consistent with that (except for when they intentionally ship older tech like in the SE)
