Isn't that number largely driven by the adoption of mobile phones, on their own cellular networks? Which wouldn't necessarily correlate with IPv6 access from Windows machines in particular.
Unfortunately, disabling IPv4 is not a viable option, unless you run IPv4 literal address translation layer (464XLAT on the server side and CLAT on the clients). Many sites still do not support IPv6, which is a great shame, but slowly but surely we’re getting there.
I tried 464XLAT on my home network, for the most part it worked flawlessy, aside from some IoT devices that don’t support v6 at all or are not LAT aware. So dual stack it is.
As I said, really not that many, to a point I was about to turn off IPv4.
Ofc, it depends on your usage.
But what's very surprising are those Big Tech sites, with billions of $ and still IPv4 only, like msft github (and github has still its core functions working with noscript/basic (x)html browsers).
What is really bothering me is the admin of the mail server of my medical insurance company: IPv4... but that's not what is the most annoying, the most annoying: it is not white listing its client SMTP servers/client emails... this is another level of bad.
