It appears that the most reliable way to detect a wildcard response for

'somedomain.tld' doesn't really exist.

Just make up a number of fake domains and resolve them. If they return the
same answer, thats the answer to change back into NXDOMAIN.

More precise: 

dig @ns.nic.nu. '*.nu' ANY

The quotes mean that the string '*.nu' will be passed straight to
the name server.
