1) Netflix account on the top end plan $15.99/m NZD (or US account which is $11.99) Older, grandfathered $7.99 plans do NOT include 4K
2) A smart TV with 4K. You cannot stream 4K netflix to a browser or other device (e.g. PS4). It will only work on a 4K TV with either smart TV functionality (or a blu-ray with smart tv functionality, connected to a 4K TV)
3) watch content that is available in 4K. obviously not all that much actually is, but most new Netflix made content is available in 4K (e.g. House of Cards, OITNB)
4) Have fast enough broadband - Netflix say at least 25Mbps is required. That requirement might be higher if you are trying to stream from US servers.

So has anybody here on geekzone actually got the confluence of all these factors and actually tried streaming Netflix in 4K?
If so, can you report on the quality. What device did you use and was the difference noticable for you?
I'm thinking of getting a 4K TV, but not sure if I can justify the extra for it with so little content available. Unless Netflix 4K is worthy, then I'm not sure I will bother.
