I have a friend who has worked on many generations of video compression over the last 20 years. He would rather watch a movie on film without effects than anything on a TV or digital theater. He's trained himself to spot defects and now even with the latest HEVC H.265 he finds it impossible to enjoy. It's artifacts all the way down and the work never ends. At the superbowl he was obsessed with blocking for fast objects, screen edge artifacts, flat field colors, and something with the grass.

Luckily, I think he'll retire sooner than later, and maybe it will get better then.
