How about some definitions here:

PKI = the set of root CAs is determined by one of a oligopoly of entities, based on CA/Browser Forum operations, where the entities aren’t really justifiable parties to the application?

Pinning = the set of root CAs is determined by the application, choosing a set of CAs specifically authorized for the application to aid in authentication?
