So far, that seems to be largely the case, with more than 50% of ASNs represented in the DFZ in IPv6, we see roughly 191884 unique destinations in IPv6 and 942750 unique destinations in IPv4 (admittedly an instantaneous snapshot a few moments ago from a single DFZ router, YMMV).
When you realize that an IPv6 address takes 4 times the space as an IPv4 address that picture isn't so rosy any more. The impact on critical-path router resources isn't quite 4x of course, but as you say: only 50% of the ASes are represented.
