I think bigger TV in the wall with a sleek wall mounted media cabinet should do the trick.

Do you own the space or rent? On my monitor the wall color does not complement the floor. The sofa is too large for the space and the curtains are too dark. Panels should be hung higher and wider than the window. You need a rectangular rug. Agree with hanging the TV and the TV console should be at least 25% wider than the TV. If you own, can you remove the cabinets that hang between the dining area and kitchen?

The room looks quite narrow. Even if you hang the TV on the wall, the distance is still very small. If you hang an even bigger TV, you'll be literally resting your face on the screen, which is not a good thing. I looked at the pictures from different angles, but I couldn't find the best way to arrange the furniture in such a narrow space with a TV. Unless you turn the furniture to the window and hang the TV on a retractable stand, so that there is at least a minimum distance between them, but then you lose the natural light of the room.
