As you note, there is no standard way to do this. I recall some discussions in the ShEx group about using some of their semantic operations to effectively frame the matched RDF as JSON, which could potentially be used to generate a frame. Something similar could potentially be done with SHACL, as it’s similar to the form-generated RDF use case in some ways, but I’m not familiar with any work in the area.
