Yep, me too - more like, if I was blind, I wouldn't notice the difference. Which is why the bitrate is always the first thing I look at when sourcing video.
But given other settings with even h.264 vs. h.265 and the source content, that isn't always a valid metric either.
I mean for fast action scenes, I rarely notice the difference between 720p and 1080p at 10ft away... but different encoding and sources, not just size alone can make significant differences.
