If you are missing bass, then you should experiment with Sub placement in your room. The Subwoofer Crawl is great for helping find the naturally advantageous positions for acoustic performance. If you've been doing recording engineering, Im gonna go out on a limb and guess you understand a little about room modes and cancellations. Just a thought to help you even out the Bass response.
Beyond that, indeed, we all have to fight a little and make compromises in our rigs. Not even considering Spousal Approval Factor!
For you, I think spending some research time looking at the Dolby specs for surround and Atmos set up will help you answer some of the questions you have... but then, checkout the Crawling For Bass video here on AH... Working with your rooms acoustics rather than against them is the easiest, and likely least expensive, way to move that along!
Cheers!
