Scroll to 7:47 in this presentation[1] and see that the different domains within the Netflix vertical are all part of the same large API, accessible from the same API gateway.
People here are making an assumption that the entrypoint to Netflix's microservice ecosystem is only for the "TV App". No -- their other domains (incl. talent and production) also depend on the same API gateway. When they upgrade the API gateway to GraphQL for one app and you might as well do it for all apps to get the benefits of the GraphQL toolset.
If their dev team believes there is value in GraphQL, maybe they also want those same benefits for their business apps/APIs in addition to their customer-facing ones. Maybe they all use the same API gateway.
I’m no expert, but as I understand it, the clients have more flexibility to request things from the backend. I don’t know the app source code, but maybe it reduces complexity in app design?
