Dear Jeff: I really don't know much about you (except that you seem to know a great deal about both the technical elements of Movies/Videos and their story aspects, plus having far more about knowledge of Welles and his work at a finger touch than I do), and so I am reluctant to raise this suggestion:
Are you familiar with the advice given in a magazine called WIDESCREEN?
The editors maintain that TV monitors are factory adjusted at far too high a level. They recommend bringing the brightness level of your TV set way down, balancing black and white, adjusting color, and they give you instructions on how to do it. They say that, not only will your TV set last at near optimum condition longer, but that you will see films much more as they were intended to be seen when made.
Knowing some of this vaguely myself for decades, without ever changing any settings, I resolved to follow their steps, and I found that, in any formatting of CITIZEN KANE, I could achieve an excellent balance for "The Projection Room Sequence," or in any film. But of course, as you suggest, in CITIZEN KANE the matter is critical.
You might want to check that out, if you have not.
