Can you confirm that this is really an “if and only if”?

Is it somehow possible under RDFS-Entailment + D-Entailment to get a value for "foo"^^bar if bar is not in the datatype map?

Would it be correct to say the following:
“The value of a literal whose datatype IRI is not in the datatype map is unknown.”
