> So I am doubting more and more the claim that iPhone is somehow IPv6 only.

as well you should. the phone has to keep working.

my point was that smartphone ecosystem is ime very well established in the v6 internet and i doubt that any carrier assigns public v4 here.

I have two carriers, one assigned v6 only, another is dual stack. My route file is much more complicated, but it might be related to both Wi-Fi calling and VoLTE.
