Most is incorrect. Many big ISPs support IPv6. The IPv6 charts notice more IPv4 when people are working, and IPv6 while people at home (nights and weekends) because so many ISPs do support IPv6 and it just works. The big cable ISPs and the big cell phone (not sure if all, but some at least) support IPv6 to everyone and have been doing it for a long time because it just works (they had to do some effort early to get it to work).

The cellular carriers are now doing CGNAT for IPv4, so supporting IPv6 means less traffic has to run through their CGNAT gear.

I have noticed that when looking at the internal IPv4 address of my phone. What's the technical difference between Carrier Grade NAT and "traditional" NAT?

From what I can tell it is just the power. Traditional/home NAT runs on low powered computers. CNAT is the same thing, but with very powerful computers with a lot of memory so they can handle thousands of users (possibly each with gigabit internet connections!) behind one IP address.
