If it had the JoAnn's 'exclusive' notice on the selvage, that would be the only place you'd find that exact fabric. Close is probably going to be as good as it gets if you want it from a shop. Sorry. You could post it on the ISO forum to see if anyone here has it in stash.
ETA:
You could also use one of the fabric search engines to find a similar fabric by typing
black circles on white in the search box.
