Some colos don't even provide v6 yet.
Some ISP's still don't suport it.
Some classes of network gear only recently got hardware v6 support. Older gear still in service pushes v6 onto the CPU. Probably why those colos and ISP's don't support it.
And I still see important v6 fixes coming in hardware changelogs, mostly on the LAN management stacks (neighbor discovery, mDNS, etc.)
That said, the pieces are finally coming together in the past two years, roughly.
I would bet 2030* will see v6 at around 75% of traffic as that old gear is tricked out and the stacks wind up in maintenance mode.
At home I actually have more light bulbs on v6 than desktops, but that'll change when my switches get too old and tired. I could replace them all right now to change but there would be no benefit to me for dropping three to four grand. None of my home use cases would benefit.
* 2038 if the politicians do actually create a global depression which is looking increasingly likely
