GraphDB uses construct queries to uplift data too

[justin2004]

OntoRefine (GraphDB's ingestion tool) has a UI that helps you generate construct queries.

The SPARQL button will open a new SPARQL Query & Update endpoint where a CONSTRUCT query based on the newly configured RDF model is generated.

Yes, it does that by default.
However, it's much faster to use SPARQL Update (federated INSERT) to materialize data from OntoRefine's virtual repo to a real RDF repo: this avoids the step of generating an intermediate RDF file.
Even more importantly, you can also use SPARQL Update to implement data update scenarios.
Eg we generate OntoRefine update queries from declarative RDF models and we use them for both initial loading and daily updates of CrunchBase data: see this

  abstract     = {The daily work of the Knowledge Graph Solutions group at Ontotext involves KG building activities such as investigating data standards and datasets, ontology engineering, harmonizing data through semantic models, converting or virtualizing data to semantic form, entity matching, semantic text enrichment, etc. Semantic pipelines have a variety of desirable properties, of which maintainability and consistency of the various artefacts are some of the most important ones. Despite significant recent progress (eg in the KG Building W3C community group), semantic conversion still remains one of the difficult steps. We favor generation of semantic transformations from semantic models that are both sufficiently precise, easily understandable, can be used to generate diagrams, and are valid RDF to allow processing with RDF tools. We call this approach "RDF by Example" and have developed a set of open source tools at https://github.com/VladimirAlexiev/rdf2rml. This includes "rdfpuml" for generating diagrams, "rdf2rml" for generating R2RML for semantization of relational data and ONTOP virtualization, "rdf2sparql" for semantization of tabular data with Ontotext Refine or TARQL. We describe our approach and illustrate it with complex and high-performance transformations in a variety of domains, such as company data and NIH research grants.},
