In the US at least, yes, because most cell providers switched to IPv6 long ago. In other places, carrier-grade NAT is widespread.

CG-NAT is widespread in the US as well, but is only used when a site isn't reachable over IPv6.

True, but in this particular context the IPs would be unique, as Facebook has been IPv6-native for many years.
