Help with room treatments


I have alot of glass behind my speakers and also a TV between (see - beauty and the beasts under systems for pics), yet my system sounds great to me. The speakers are forward of the TV by at least 8 inches.
After hearing all the stuff here about room dynamics, today I placed very heavy blankets over the windows behind and also over the TV to see if acoustic absorption panels may give me better sound. I did not hear any differences on several of my favorite test cuts in near field listening.
Could it be that my SRS-SDA Polk speakers are better than most at eliminating the reflections given that they phase cancel signals coming from the left speaker to the right ear and vis versa for the left ear?
Or am I that untrained to hear differences. I think I have good ears, am a musician etc. Perhaps I picked up very subtle increase in the solidity of instrument placement. but that is all I heard.
Comments?

Thank you for your responses. With the speakers about 8 feet apart, I am listening at 10 feet with couch cushion diectly behind my ears. I used Opus 3 Test CD 4.1, for timber, balance and depth. Sound field is very wide, extending well beyond the speakers, depth is Ok with definite layers of instruments in front and behind. All seemed pleasing and pieces presented as the disc described they should. No unevenness on piano and voice noticed, things sounded silkly in the high, clear in the mid, and tight and solid in tone and position in the base.

Thank you for your comments. It helps me understand my blessings and why things may be happening the way the are.

Thank you Mikelavigne for your kind comments and suggestions. The TV isnt likely to go anywhere at 220 lbs., but I can try blanketing it. Also I will try a temporary blanket/quilt on the ceiling. (some day when the wife isnt home:) If it works, do you know of any attractive acoustic panels that might attach directly flush with the celing?
I am familiar with Duettes and do find them attractive and practical. What are the likely drawbacks to a wide speaker baffle? I think you are probably correct that the wide baffle is saving me from expected reflections from the windows and TV.
