In data centers we are used to that IPv6 is cheaper, IPv4 addresses cost real money. If IPv6 only were cheaper for consumers it would make a difference for them.
But maybe that's really only relevant for routable static addresses and consumers typically don't need any. I understood e.g. T-Mobile US consumer subscriptions are IPv6 only already now. (Not living there, so from hearsay) It's just transparent to the customer via NAT64 where needed? And obviously all somewhat recent phones just work, so no logo required.
