It seems to be pervasive for people to grossly overestimate the savings they can get, looking e.g. at how MPEG-4 TV channels are generally lower quality than MPEG-2 channels. And the biggest HEVC torrents are at most less than half the size of the AVC torrents, usually only like a quarter the size.

The MPEG-4 transition was the worst. "Ooh, look, we can now squeeze 4 more channels into the bandwidth of one!" ... yeah, at half the quality.
