The vast majority of consumers don't know or care about IPv6.
There seems to be more competition here in France than in the US but while I've previously used ISPs with IPv6 support my current one does not. Even as someone who prefers to have IPv6 it's not something I considered when signing up and I probably wouldn't pay much extra for it, as a consumer.
Symmetric bandwidth and connections for anything more than a personal server are available here but only on business plans. Those are easily more than 10x consumer prices so I can't imagine going for them unless you need the SLA's.
