You may be interested in checking out https://www.youtube.com/watch?v=lhVGdErZuN4, where I talk about the benefits of Relay. This isn't (currently) possible without GraphQL, so it's a pretty compelling case for GraphQL.
But yeah, IMO, GraphQL doesn't justify itself unless you're using a client like Relay, with data masking and fragment colocation.
That is an interesting talk, thank you!
