Although I am not in a position to have a room professionally analyzed and treated I think it would add a lot to the presentation and you would be able to listen to any gear or music and have it played back as it was intended to be.
A massive number of excellent brands/products here. Baux are particularly good.
I also used this stuff extensively, which absorbs as well as blocks.
It turns out that our main listening room isnāt a candidate for room treatments. Based on our room layout and all of the various items in the room including built in bookcases, furniture, art, curtains, shades, etcā¦thereās no room other then the ceiling to put any treatments. Ceiling treatments are not an option based on the over the top of eyeglasses glare I received.
LOL.
I am pretty much in the same boat. I did manage to get the OK for some heavy drapes over the windows and Boss Lady has some new furniture in place.
Although I am certainly no sonic expert the system does sound pretty darn good. Would it be better with treatments? Maybe but not worth the aggravation.
I do have an empty basement that I could move the stereo into but I dont really want to do that at this time. Maybe sometime in the future that will be more enticing as it is a pretty empty space with bare walls, bare floor, and open joists on the ceiling.
I am poking at putting a second two channel rig in my office to have a system that I can play with treatments. My current office system is setup for near-field. It sounds fantastic. But, if I want to just sit and listen, itās not as comfortable as sitting in an Eames recliner and at my desk thereās the distractions that come from having a three monitor workstation.
Ultimately, this is simply an excuse to have a new toy to play with. 
Heres is one way to get that special sound. A nod to the Stanely Kubrick 2001 aesthetic as well. Canāt vouch for the speakers, but a custom upgrade may make it more desirable

I had an egg years and years ago when I was groovy. I need to dig around and see if thereās a photo. It worked, but it wasnāt the most comfortable.
I am not mentally able to listen to music and work. I guess both music and work require too much of my brain power such as it is. I just use a set of Bose or similar powered computer speakers as I dont get much time to listen at work.
We use 4 monitors at each workstation. A pair of 32" Samsung curved in landscape mode in the middle and a pair of 24" flat Dells in portrait mode on the ends. The portrait mode works well with text based apps and web pages. The 32" in landscape work well for CAD and CAM programs. Can you say head on a swivel?
They were a huge hit in the day at our local library. Bit of a novelty to be sure.
I have a tag in Roon thatās labeled āMeditativeā. Itās mostly comprised of ECM recordings, primarily Scandinavian Jazz. I find it creates a bubble around me.
Iāve gone a similar route as you with monitors. Center is 38" flanked by two 27". Between the 27" and the 38" sit my ProAc Tablette 10 Signatures on stands.
Back when I was part of the working class, if I was playing classical music in my office, it meant āenter at your own riskā; sitar music was ādo not enterā; no music, pop/rock/folk or NPR news was ācome on inā. My wife on the other hand has to have absolute silence and blinds drawn at all times!
Itās really a lot more productive to have a desk full of monitors as you know. Much easier to have a whole lottaā projects working and be able keep up with it all.
The perfect opposite of me is my son. He can listen to a podcast on wireless buds, play relatively loud music thru his desktop system, program and keep 3 or 4 machines running all at the same time. I cant even enter his space without getting confused. Age might have something to do with it
