Yep. Other options though, might be to have new sections on the home screen similar to recently added TV or Movies. New on Hulu, Netflix Watchlist, etc.
Alternatively they could have labels under each poster labeling it as Hulu or Netflix, etc. A customization version if this is something I’d like to see anyway. This might be the ideal solution because then no matter where a poster showed up – On Deck, Watch Lists, or Playlists, or unified search results – the branding would stand out.
