My guess is that your method was:

100% = all unique IPv4 addresses visiting the site

working v6 client: gets the v4only pixel via v4 and the v4+v6 pixel via v6
(so you can correlate the v4 and the v6 ip)

broken v6 client: only gets the v4only pixel and not the v4+v6 pixel.

(I work at a university where I am pushing an IPv6 project. Repeatable
research like this is how I can get researchers involved)

I asked someone about the date of the introduction of vista. He said it has
been around for about a year. I can't say there is a sharp rise in broken
v6 clients. And he wasn't aware of any real IPv6 problems in Vista when
there is no v6-connectivity.
