Has someone done this sort of analysis" on YouTube? Anecdotal: Even though it claims it's giving me the 1080p resolution, everything still seems blurry. The only time I get actual crisp visuals is when I watch a 4k stream and "down scale" it to 1080p. I feel like they're pulling a fast one on us.

You're talking about a different thing, compression bitrate and artifact.

Take a 4k video, encode it into 320p, then encode that into 1080p. For the matter of what they are discussing, your video file will be true 1080p. For the matter of what you are discussing, that video will be horribly blurry and full of artifacts.
