Why are Blue Ray's sound all over the place?

5. I was reading about the Apollo 11 Blu-Ray disc...

... it's only got the theater version of the audio track, which is fine if you are in a theater, or if you like to tinker with your own home theater audio setup. (The sound in theaters is set up and maintained by full time technicians who travel from theater to theater.)

Some of the voices on Apollo 11 are muddled because they are taken from the original archival tapes.

Looking through home theater discussion boards it seems that many Blu-Ray discs produced for rental don't include the theater quality audio tracks because they have to sound acceptable on the older or lower priced televisions and Blu-Ray players most people who rent movies have.

My wife and I are Luddites. We watch DVDs and $8.99 a month "Standard Definition" Netflix. We do have a 1080p television but it rarely sees any HD content and we don't have any external speakers connected to it.
