Have you tried logging into Playstation.com and viewing your download history? When you are there you can push a download to your console. If the Wolf is setup to be available on both PS3/PS4 (which I know that it is supposed to be) then you should be able to push it to the PS4. Of course, if it's set up wrong and not available to push then you have a bigger problem to solve.
I don't think it can be carried over
