My only other possibility, which I don’t really think would work is the wall to left of the picture has a gas stove sitting on a brick hearth and the brick runs up the wall to the ceiling. The stove has a flue that comes out the top about 2 feet, turns 90 degrees. And goes through the brick. There might be barely enough room to mount the tv to the wall, if it can be mounted to brick somehow, but I would assume the heat coming off the stove and flue would not be good for the tv.
