@pug987:

I know this is an old post, but it's not all about pixels, but also about bitrate. Netflix's 4k video has a higher bitrate than the 1080p video. For example, how a Blu-Ray 1080p video looks better than a streamed 1080p, because Blu-Ray movies have a higher bitrate. Because of this, I think a 4k stream on Netflix would, in fact, look better than the 1080p stream, even though it's not showing all the pixels.
