I'd assume a lot of this is because of mobile devices of some type. Getting legacy network operators like cable providers to supply IPv6 has been hell.
Eyeball networks and cloud providers have been implementing IPv6. In the US all major phone carriers are v6 only with XLAT, the large residential ISP all have implemented v6 (Charter/Spectrum, Comcast/Xfinity, altice/optimum). The lagging networks are smaller residential ISP and enterprise networks.
In Asia they've implemented v6 everywhere pretty much because their v4 allocation is woefully insufficient. APNIC has like 4 billion people in it but less IP space than ARIN, with a population of less than 500 million.
Well the data shows they are in fact using it. Most people use their ISP router which in these carriers would be setup by default to use v6, plus any router bought in the last 10 years would support v6 and probably use it by default.
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
