It seems the Old Ones were in other galaxies as well at the time, or atleast had minor colonies in galaxies such as the Andromeda Galaxy. The Old Ones might be considered the pentacle of type II since they could gather power from alternate realities such as the immaterium. Intresting to note though, apparently a Type III civilization may also build a Dyson Sphere large enough to enclose an entire galaxy! If the pure immaterium covered the entire Milky Way invisibly, then that qualifies the Old Ones as an upper Type III.

The scale can go past Type III since extensions were made to it, but a Type IV civilization is extreme in that they can control the power of an entire universe with a Type V controlling multiple universes, no civilization in 40k goes past upper Type III, but then we must ask if the warp expands to other galaxies, in which the Chaos Gods, or other Chaos Gods have control of, if that's the case, Chaos might be considered Type IV controlling an entire universe.
