Technically CloudFront requests to the origin server are IPv4 only, so there's still IPv4 in the stack even if the distribution has IPv6 enabled.
Personally this is one area I'd like AWS to focus on, along with load balancers listening on IPv6 only (currently it's dual stack). Every load balancer we deploy takes up at least 3 IP addresses - I'd quite happily switch them to being IPv6 only if CloudFront could access them over IPv6.
