If they stream 1080p at 6mpbs, I doubt that streaming 4k at 16mpbs have any sense, probably marketing dictates them to do it. You could get more quality by increasing bitrate without any hardware hassle. Content producers spend much effort and money to create HQ, high-bitrate picture and then you flush it down the toilet scaling to low values. And post production for 4k image is much more compute intensive and much more expensive.
