I think the easiest would be to create two instances using those schemas and then see what comes back from schema API: http://lucene.apache.org/solr/guide/7_4/schema-api.html#retrieve-schema-information
That will give you the outputs in the consistent format, you can just run diff on. However, if you want to actually do a graph analysis on explicit+dynamic fields -> definitions, then it is a bit more work. Doable, but is a mini-project. I did something similar before, but the code is not open-source at this moment. And it really depends on what _very specific_ question you are trying to answer. For example, it is not clear whether any example schema dynamic field should be part of the "used" calculation just because it exists... Regards, Alex.
