In other words, movies are not intended to be played back at devices that aren’t connected to theater-grade audio hardware.
Of course this requires the question of why movies are even released on Blu-Ray, DVD, or streaming services at all instead of just using the existing distribution system for movie theaters. Everyone who doesn’t run an IMAX setup at home is too poor to watch movies.
By that measure, most movie theaters also shouldn’t be showing movies – very few of them have the precise setup a given movie was mastered for. If the movie was made with IMAX laser projection in mind, it should only be down in theaters with such projectors even if this excludes 95% of theaters. Likewise for rumble seats. Or theaters with Atmos sound systems if the movie was made with DTS-X in mind.
Of course this leads to the conclusion that it’s financially unwise to release movies at all because any movie will only ever be able to be shown in very few theaters and will not recoup its production costs.
Or, you know, you release it for multiple projection and sound setups and accept that there is a close enough level of fidelity for a given use case. Which leads us back to actually properly mixing it for the home release because the people who have IMAX laser 3D projectors and 12,000 W sound systems are not going to be using Blu-Ray in the first place.
