Actually not, and for good reason.

The question you are heading for I think is the question of when is
something a single dervied work or not.

In the software case I can't use copyright law to write an editor
and forbid you from writing proprietary software with it. In the
artwork case you can't stop me loading your NC photo into a non-free paid
for app.

There are cases its annoying, there are cases where the boundary in law
may well be dubious, and certainly the boundary in question is at best a
fog not a line. There are however lots of cases where such degree of
control would be objectionable to society. Imagine if Windows could
forbid viewing CC content !

I would personally be very surprised if a game that was no use without
that artwork was in fact multiple independent works but I am not a lawyer
and this area is definitely a lawyers minefield.

Also if the issue is the boundary of copyright and what is a work then a
copyright licence cannot I think fix the problem.
