I'm on a large ISP provider and they do not have IPv6 in my area, a new build with fiber to a access point that turns it to cable on the house. So there's that.
Ah RFoG. It's a weird technology choice. I think it's supposed to be transitional so they get the fiber in the ground now and then can later come back and rip out all the DOCSIS equipment and replace it with *PON
