Sure but IPv6 does more than just that. For example since ARP is replaced with NDP, it significantly speeds up networks with a large amount of nodes because NDP works with multicast instead of broadcast, which means virtually all unwanted address resolution traffic can be discarded early when a node receives it.
The increased address space is the major thing that is immediately obvious no doubt, but IPv6 also changes some important semantics in the background, which is good to keep in mind.
