Flatscreen between speakers

Has anyone found a solution to cancel or at least improve the acoustic glare caused by a flatscreen tv on the wall behind the speakers? I don’t have a dedicated room and have to share the room with my home theater setup. I have thought of using an appropriate curtain and treat the tv as if it was a window. I am also considering light 3D printed panels that I can temporarily hung when listening to music and take down when watching TV with the wife. 
I tried hanging a couple of thick towels on it to see if there would be any improvement and the answer is yes. The center image is more solid and a little deeper. Nothing drastic but if I could squeeze anything positive, why not. Please let me know if you have confronted this issue in the past and whether you were able to solve it. Thanks.

Other than having a flat screen between your fronts, instead of diffusion panels, I am not aware of any other compromises.

Each system runs completely independent, with the exception of the fronts & front amp via HT pass through. I have an SQL sub for 2 channel and a SPL sub for HT.

Any compromises were more around what I was willing to spend. And I love to watch sports while streaming Qobuz.

I asked Google Gemini for treatment options. One of the options was using sound absorption to the left and right, behind and below the wall hanging TV.  I used 24x48x2 panels (thicker panels would not fit behind TV) extending behind by 3” & below by 5”. Gemini claims this largely mitigates the problem. 
It recommends experimenting with speaker distance (mine are 30” out) from rear wall and ensuring there is no resonance from the TV & mount. Since the bottom of the TV rests on the absorption panels, that should help mitigate any resonance. 
Lastly, it states ’if you want to go the extra mile’ try placing thin removable panels or dense velvet/felt over TV during critical listening. Hope this helps.
