A toString() buried down in the code was it. Simple to add the
datatypeURI. Thanks!

OK the documentation is not exhaustive... The 1-argument
createTypedLiteral() attempts to infer the RDF datatype from Java
type, where 'objectDataValue' is a String I'm guessing? Which becomes
xsd:string.
If you want to override this with an explicit datatype URI, you need
the 2-argument version:
Literal dataLiteral = resultGraph.createTypedLiteral(objectDataValue);
System.err.println("objectLiteral: " + objectDataValue + " " +
dataLiteral.getDatatypeURI());
always says type is http://www.w3.org/2001/XMLSchema#string

If I reconstruct using
Literal dataLiteral = resultGraph.createLiteral(objectDataValue);
it always says the type is string

I think DATATYPE() is what you are looking for:

What is the best way to reconstruct a typed Literal from a SPARQL SELECT
result?
I have a SPARQL SELECT query issued against an OntModel in this way:
QueryExecution structureRowsExec =
QueryExecutionFactory.create(structureRowsQuery, owlOntModel);
Here are some example triples in the
