...that provides a better 3D visual perspective of how my system interacts with surroundings and 20' ceiling.
The one mildly frustrating aspect of this arrangement is a filtered air return on the upper left front wall (out of view, above the speakers). When the central air conditioning clicks on it adds noticeable background noise while running. This isn't totally distracting, but it is a occasional annoyance and there doesn't appear to be a solution that retains temperature control.

So the screen fabric is acoustically absorptive rather than reflective?
The screen is usually back (close to the FW) when listening to music without video. In that position the screen helps break up and diffuse sound waves, but it's a reflective surface. My photos may not convey how this works as clearly as intended; sorry 'bout that.I'm not saying that this set-up is 100% perfect, but it works very well for personal music enjoyment given the reasonable compromises required for HT and group entertainment.

I am thinking that you would benefit from diffusion panels behind the speakers and to adjust them again to minimize interaction with the screen, possibly using it to control backwave radiation from between the speakers (move the speakers backwards a bit) and either use less toe in or an absorptive foam at the inner edge of the speakers to prevent flat angle reflections from reaching the screen.
If you pull the speakers forwards substantially, you will need to do so to a great extent unless you use the fake ficus trick to diffuse the backwave before it reaches the screen so as to avoid a recessed center image.
Thanks for the suggestions. Appreciate the ideas!
I should probably mention that this (the above image) is where the screen is usually located.
For music listening or sweet-spot viewing I normally move the screen back to the wall and refocus my HT projector. When we have friends over to watch movies I bring the screen forward (to the position in the earlier overhead photo) and adjust the projector for a shorter throw. That increases side viewing angle otherwise blocked by the speakers.
When close to the wall, the screen helps break-up and diffuse sound waves with negligible loss of center image.
