Your room is an echo chamber period. You need at least a large area rug and probably more. There are way too many hard surfaces and not enough compensating absorptive ones. All of those hard surfaces accentuate higher frequencies making the sound thinner and brighter than it should be. Also imaging is bad because of all the reflections blurring things. Depth is lost for the same reason.
Do the following:
1. Get a LARGE area rug
2. put sound treatment absorption/diffusion on the wall between the speakers where the TV is. Your best bet would be a cover over the TV that is easily removable.
3. Experiment with some small treatment that would at least diffuse (possibly absorb) reflections from the window right near your head.
