I think they'll eventually notice a difference. How will an IPv4-only internal host know what to do with an IPv6 AAAA record it gets from a DNS lookup?
If the CPE is doing DNS proxy (most do) then it can map the AAAA record to an A record it passes to the internal client, with an internal address for the record chosen from RFC1918 space, and perform IPv4-IPv6 1:1 NAT from the assigned RFC1918 address to the external IPv6 address from the AAAA record (since you have at least a /64 at your CPE, you can even use the RFC1918 address in the lower 32 bits.... :-P). This may already be a standard, or a draft, or implemented somewhere; I don't know. But that is how I would do it, just thinking off the top of my head.
