High dynamic range sound mixes have been with us for a long time. Have you ever watched Lawrence of Arabia in a movie theater? If you do the mixdown to stereo poorly and/or refuse to compress the DR and then play the result from built-in TV speakers I guarantee that you won't be able to hear the dialogue at an acceptable volume even though the film is from 1962 and features clearly-spoken lines from former professional stage actors.
