Isn't the presence of an AAAA record but the lack of an A record already a sufficient indicator that the service is IPv6 only?

It should, but:

* I don't know any browser or app that display a special, informative message in that specific case.

* You need a DNS server that answers AAAA record to detect this. Some ISPs do not provide IPv6 connectivity, nor do their DNS servers provide AAAA records. In most places I know, especially when talking about individuals, people use their ISP-provided DNS servers.
