That's great!

One way to know, is that if you follow the general recommendations of the microdata to RDF specification [1], you should generally be able to translate microdata to RDF. Since JSON-LD is a serialization of RDF, this will show give you an idea if you're conforming at this level. There is a test-suite [2] you could use to take the generated JSON-LD and turn it into RDF and then see if it matches the test output.

The other way you could do this is to just use the playground, or some other tool, to translate your generated JSON-LD into Turtle and visually compare output of different microdata sources; the examples from schema.org are the relevant ones.

I'm not sure in particular what your asking here, but in general the output looks pretty good.

Great job!
