By "fuzzy" I mean resolution that is too low for either the size of the screen or the distance one is sitting from it.
High(er) resolution can look great, or near great, for all viewers at any home screen size or any home viewing distance. It's just plain a more versatile way to transmit a video product for as broad a customer base as possible. There is no substitute for higher resolution and a full color spectrum.
FWIW, some prefer a viewing experience that as close as possible matches what they see through their own eyes in real life - as if a "screen" wasn't there at all. The sourcing and receiving technology for in-home and in-RV viewing near to that is now available and affordable. Of course, many viewers still only feel that they need good enough video.
