Harold, I had the exact opposite effect with the Sound of Music...it is an example, for me, of dialog panning done right. Fixed center dialog I find jarring (the bigger the screen the more the voice sounds disconnected from the image). There are techniques that are required for panned dialog just like there are things like the 180-degree rule for shooting image to avoid disorientation. 2001: A Space Odyssey is an example where the panned dialog is not always shifted to avoid calling attention to itself (the telephone sequence comes to mind where there are numerous cuts and instead of shifting the dialog to Left, they left it at Left-Center).
As for Perspecta. It isn't just shifting the audio. You have a mono track with three faders (while mixing) so you can place the audio in any combination of the three screen speakers. It is not a mere pan-pot. So, if you do have music, you would, back the, likely mix it to all three speakers to give the feeling of filling the stage but would have to temper that with what else is going on since you don't want dialog coming out of all three and you don't want the music to collapse every time someone speaks. I suspect that there were certain sequences where they decided that they wanted directionality and tailored the mix to allow for it. I've only heard a handful of Perspecta tracks but they were better than they should have been given that all they had to work with was mono at varying levels out of three speakers.
