I can appreciate your enthusiasm and drive to improve both the measured the overall subjective listening experience.
I mentioned the suggestion below, in a previous post, is this a possibility? Many rooms just don't lend themselves to a slight rotation due to aesthetic concerns, foot traffic, etc. But if possible, if you could slightly shift the entire set-up, creating an angled boundary adjacent left and right to the loudspeakers. This redirection of the sidewall energy allows the recorded event and image recreation to be fully resolved in your brain, quite similar to what the engineering team experienced and much closer to what they want the user to experience.
It's all about the Initial Time Delay Gap, or ITD gap. This is essentially the time difference at the listening position, between arrival of the direct energy, and the first strong reflection. The reason we want a longer ITD gap, is simply to allow you to hear the time domain localization cues that our listening process needs to recreate the image. SBIR, a separate issue, but a potential by product nonetheless, is the smoothing impact in the freq domain.

fwiw, different topic ... in such lack of symmetry room scenarios, such as this (right up against right wall, rear wall), you may examine the possibility of rotating the entire operation about 45degrees. Placing the display and focal point in the corner, this removes the L-R asymmetry, and re-directs sidewall energy behind you (studio technique). Just consider it, it may not even be an option and that's cool. Your existing set-up is very clean, very nice. I'm looking at the overall approach from above, .. thinking about what improvements are possible imaging wise, which subjectively would pay off wonderfully over time, if it was better.
Just suggesting to think about it. Nice system, and the room, and it's interaction is of huge significance to the experience.
Best of luck
The Left-to-Right symmetry is very important, and quite likely one of the most important elements in the playback experience. Outside of studios and dedicated rooms, it's tough to fully pull off in residences and multi-use rooms. However any efforts directed toward more symmetrical environment will pay off huge, I assure you
Another by product of a set-up shift, would be the area behind the listening position, expanding it and allowing again for more path distance of the energy...smoothing response/comb filtering etc., and again more imaging detail.
Yeah, one can address the ITD gap with absorption, like the vast majority do (myself included, no choice). But angled walls, or angled set-ups and redirection off lateral energy is the preferred method to create a sufficient gap between the direct energy and the first strong reflected energy. It's preferred because it doesn't filter the reflection like an absorption panel does, and maybe more importantly the precious lateral energy is preserved but added back in later thus creating great spaciousness, immersiveness.
Hope this helps, let me know if you'd like more specifics.
Best of luck.
