Can you take a picture from further back so we can see the whole wall?

From what I can tell, simplification is in order. Remove the square frames, and remove everything from the top of the tv cabinet.

The frames on the floor were on the wall so they will be removed when the decision is made. Lamp will not remain on the floor.

I think it is unnecessary. You have enough decor in the room. Eventually maybe get a larger TV

Those floating shelves near the chair should be on the tv wall.

I would choose the round ones - too linear right now. We chose round decor next to our TV for the same reason.
