I think you can easily jump from a 5 to a 10 with room treatments or DRC. Break in will get you nothing in my opinion as for the most part it is a bogus term. The only thing breaking in is your ears to the sound.
Sounds like your dealer is awful too btw.
If I am you I am going to look at digital room correction and see what that does. Even if you just try it as an experament. Room correction can have a huge impact on the sound- especially when trying to clean up muddy midrange and bass. It will also do level balancing between channels and since you have no side walls should dramatically improve imaging. The rear wall must have a huge impact on sound so I would make sure the curtains you are using are heavy enough to properly damp that reflection. This is where your "layers" are most likely getting lost.
You could also do acoustic treatments but your room is so nice and minimalist I would want to see what DRC did first before bringing ugly treatments in.
You have way to much invested to have anything but spectacular sound.
