The provider who gave me the information didn't tell me what public route
server they used. They didn't analyze all ASNs, just the handful I listed.
It would be interesting if someone set up a daily report that documented all
the IPv6 routes an ASN carried, and then tracked both the absolute numbers
and percentages over time.

Not sure what route-server you are speaking of, but a quick peek at what we
send on a customer session I see:
NTT (2914) sends 3868 prefixes.
If the route server contacts me in private, we can likely set up a view from
2914 or 2914-customer perspective.
