I would not call this is_subdict. That name does not
clearly express that all keys need to have the same
value.

set(subdict.items()) <= set(reference.items())

should be equivalent to your code

if you only want to check for presence of all
keys in the reference dict:

set(subdict.keys()) <= set(reference.keys())
