in both cases the client has no IPv4 address and all communications
happen over IPv6 only.
However there might be additional services provided to allow access to
non-IPv6-enabled destinations. It might be a service provided by the
network (such as NAT64+DNS64) or it might be smth on a host itself
(464XLAT).
So in general I'd expect the term "IPv6-only" to cover both a) and b)
as b) is just a) with an additional service on top.
