I would be quite happy to be proven wrong and only time will tell. =20Almost every client does have a strong IPv6 bias if they have what appears to be native connectivity. The bias degrades rapidly with other forms of host connectivity. My linux and Mac systems certainly seem to strongly prefer IPv6 from my home. YMMV.
Things like happy-eyeballs diminish it even with perfect IPv6 connectivity. 100ms rtt doesn't cover the world and to make multi-homed servers (includes dual stack) work well clients will make additional connections.
