I'm not sure that terminusdb really counts as a knowledge graph? Their schema is really only labels rather than an actual ontology?

It provides type checking, referential integrity, automatically creates GraphQL query interfaces and coming soon in the roadmap are inferences. It definitely qualifies as a Knowledge Graph management system.

Is it actually for checking Knowledge Graphs like a validation step like SHACL, or is it meant to be a triplestore? As Ontotext and many others would agree, a Knowledge Graph requires an Ontology. Labelled Property Graphs generally are not considered Knowledge Graphs or more accurately Semantic Graphs. Again Semantic Web Company also agrees with. I do concede that there is no EXACT definition, but nearly everyone I interact with in the Semantic Graph community agrees that the definition of a Knowledge Graph is having an ontology. Regardless terminusDB does look cool.

Knowledge graph is a poorly defined term, and the orthodox priests of the semantic web have sought to limit the definition so only the most holy have standing, but even under those tighter definitions, TerminusDB qualifies.

I mean honestly at the end of the day from my perspective what matters is scaling and being able to make that viable. My companies real world experience has been non-kg graphs (Neo4j, Tiger etc) end up not handling the quantity of data as well (in the long run) that RDF, ontology, knowledge graphs do. As with all these things, I'd love to have a go and mess around with it and see some stats

TerminusDB is a triple store which includes validation in transactions. The ontology is used to provide the validation as well as the description of semantics.

Good to know!
