An ISP probably already has IPv4 addresses, but needs more addresses for basic connectivity. They can become IPv6-only and then use their IPv4 block/s for CGNAT. The money would go to either buying more addresses or more CGNAT.
This is how a lot of mobile/cell telcos already work. A T-Mobile presentation from 2018 (PDF):

Running an IPv6 core and offering IPv4-as-a-service doesn’t really make you IPv6-only.

I'm not sure what you're referring to.
Here's a dude from T-Mobile explaining how they have (in 2017) over ten million end-customer devices without any IPv4 addresses assigned:

For reaching services that are IPv6 only they use(d) DNS64 (with and without 464XLAT).

IPv6-only as a term has been heavily abused. A truly IPv6-only network has no access to IPv4 resources. If it does, it isn’t really IPv6-only and relies upon IPv4 addresses and NAT to work.
A single ISP can't do anything about the situation. They can provide IPv6 to their customers, but they still need IPv4 so their customers so they have a usable internet connection. It doesn't help them at all.
Which is part of the problem here: As long as IPv6 is not implemented by everybody the people who do implement it have no advantage.
