As I have posted before I have watched 80 UF movies of the 99 movie promo I bought. I compared NF native HDR 4k content with my slow bandwidth 6-8mbps sustained. Quality is comparable or even better because of HDR enhancement as to our 4k like "The good year" which is shot in 4k. The gap is closing or it already is. The 25mbps is old news. NF must have found a way without buffering.
