> A 4K netflix stream caps out around 15mbps

Yeah, but that's just because Netflix streams are ridiculiously over compressed -- they use extremely low quality encodes. It's technically a "4K" stream, sure, but at a bitrate only realistically capable of 1080p.

An actual 4K stream (one capable of expected resolution at 4K) is around 30 to 40mbps.

Back in the day, it was better to upscale netflix's 720p to 1080p than to stream 1080p.
