Yes in Lon's YouTube review he talks about support of 4K/UHD Netflix, although this was on pre-release Firmware and 4K Netflix had an occasional video glitch issue.
Also, we now know, that even though Amazon Instant Video is not supported. If you sideload a Sony TV - Android TV OS - AIV App, you get 1080p video output (audio 2.0). This is only for those Android devices packing proper DRM approvals like the nVIDIA Shield & WeTek Play2 (Hub to be confirmed).
I would expect expect the Mi Box to be able to do the same as it should have all the same DRM approvals.
