I wouldn’t be so sure, the baseband firmware can be remotely updated by the carrier.

  In addition, most carriers have settings inside AOSP itself. I remember when I had an International Galaxy S7, I'd see 4G if I connected to a carrier that used that branding for LTE (like AT&T) and LTE for others (like T-Mobile).
