Is HBO consistently doing OAR now? Last I heard (earlier this year) was that they were only doing it per studio request on specific films. The sad fact is that most people don't care or even prefer viewing a scope film cropped to flat. Largely the same type of viewers that can't tell the different when motion smoothing is on.

My other annoyance is the rising prevelance of 4K streaming, when the picture needs to be compressed so much to smoothly stream that the artifacts completely outweigh any kind of resolution advantage. There's no point in having that much resolution if the picture is going to have blocky artifacts popping up through the whole runtime, however subtle they may be. Give me bluray anyday.
