I don't have the Netflix 4K either because I don't have a 4K TV. Now, to answer your question, I just tested that from my Hopper 3. When I went to Netflix my TV immediately told me that it changed from 1080i to 1080P. When I went back to Dish TV it reverted to 1080i. So that is the answer Netflix is 1080P.I don't pay for the 4K Netflix (yet). So what is the resolution when watching on the Hooper 3? Am I at least getting 1080P?
I have doubt if not subbed to 4K you get it. Thing about many devises they tell you what you want. My Sony shows 1080i even on channels I know are only 720p broadcast like ABC, ESPN...( just example).
