I agree with the "if it's not broken ..." comment, but for whatever use it may be to you, I have a large TV set pretty well on the floor between my speakers, back from their plane about 1.5', and found that things improved if I put Argent Room Lenses (actually my own DIY imitations) in front of the TV. I found that two Lenses were better than one, so I made a 7-tube Lens, with tubes a bit higher than the TV. It's easy to move for TV watching, and did help the sound quite a bit. Reflections come from everywhere, roughly, and while you don't want to eliminate them completely, most do more harm than good, especially in a smallish room, I think.
