That’s a cool room! I’m working on something similar, and yeah it will also break a lot of acoustic room treatment rules.
Pretty much everything has been said, but I’ll add my 40 years of experience here:
(1) At the level of gear you have, a "remarkable" improvement is going to be hard to come by. Synergy between components is important, and that can’t be taken in a single step. It requires auditioning gear within your system from a dealer that trusts you’ll bring it back or pay for it. Andy at Saturday Audio Exchange has let me audition endless pieces of gear and it’s a lovely way to build the system. But anyway, my main point here is that improvement takes time and work and is thus usually incremental, not dramatic.
(2) You would benefit from acoustic modification to the room. But it doesn’t have to disrupt anything - you need to take it as a challenge and get creative. Get the Metallica logo printed on a giant set of drapes and then you can take down the poster...no loss then. Bass traps in team colors, etc. You want remarkable improvement, then you’re going to have to put in some remarkable effort. Good audio isn’t $$.
(3) You said you’re not looking for more bass, but I am a big fan of REL subs for this reason - they are not really tuned to make explosions in movies move your couch. They add "air" to the room and I often find the biggest impact of the good REL subs is on the vocals. Part of the REL goal is to pick up the frequencies that create hints around the physical space where the music was recorded, and it can sort of take you away.
(4) If you already love your system at high volume and it is low volume where you want improvement, this you might be able to force without finesse by adding a small integrated tube amp and near field speakers near your seating area. It might be hard to extend out the sweet spot from your main system.
(5) It doesn’t look like you’ve placed your seating area to be in the sweet spot, as above, or at least your room implies you may be listening from a number of different stations around the room. Not that I think gear is your issue, but dipolar or bipolar speakers tend to have a wider dispersion of listenable sound. Consider a pair for when you’re not sitting still in the sweet spot.
(6) Source can give dramatic upgrades too. I don’t know the Lumin gear but I do prefer the non-MQA Qobuz sound.
(7) One more idea just for fun: get yourself set up with a reasonable 5.1 system and start collecting 5.1 channel DVD-Audio, SACD, and Blu Ray disks. Now that is a remarkable improvement, and with just the built-in room correction on your AVR, it somewhat defeats the issues with your room.
Sorry for the tome, I guess not everything had been said.
Oh yeah, and good weed.
