Depends on definitions, but if you go with 10 as your base for "orders of magnitude" and 64-bit prefixes as "one IPv6 address" (which is the intended amount of address space for a single host), it's pretty close to precisely the same difference of scale. If you mean every possible 128-bit address of IPv6, then IPv6 wins by another 20 orders of magnitude.

EDIT: of course, space wins either way if you count volume rather than distance - the "orders of magnitude" compound additively. and I also doubt that "one scrollbar unit" corresponds exactly to a power of 10, so it's still a weird comparison.
