I checked trough the compiled app with one of the two esn's you provided psycon in this topic, when using my GTV esn it spit out an error and would not launch(error -130. both the testvideo and the info button on the remote say 1080. On the kodi app it would not even launch it gave error -133.What do you check through? In Kodi or in the Netflix app? If in Kodi, then this is normal and you have 4K, and if in the app, then the test video is incorrect or some do not have it at all. Here you can focus on your router's traffic. And so 4K works great, again, if you purchased a plan with 4K.
Image one says UltraHD 4k but both testvideo and info screen say 1080.
