I understand that it dynamic range is necessary and having none is terrible (look up "loudness wars" in the recording industry), but it seems TV shows are no longer mastered for a actual home consumption.
Back in the day, we would work on our nice studio monitors, switch to a pair of NS10s to make sure it would sound good on a cheap Hifi, but we would also make it sound good on something garbage. Sometimes (always in fact) this was to the detriment of how sound on good gear, but 99% of people use garbage.
