Have a look at __spec__, specifically __spec__.origin:

>>> import sys
>>> _fi = sys.modules['_frozen_importlib']
>>> _fi
<module '_frozen_importlib' (frozen)>
>>> _fi.__spec__
ModuleSpec(name='_frozen_importlib', loader=<class
'_frozen_importlib.FrozenImporter'>, origin='<frozen>')
>>> _fi.__spec__.origin
'<frozen>'

I've not looked up in the importlib docs to confirm, but that should
mean that frozen modules should have a __spec__.origin that contains
"frozen".
