I would not put wood on the wall.

Why does the wall need to stand out more?

Lower the TV so it is ~5" from the top of that tall side board. Move the stuff off of it and put it in a book case beside the TV.

Lower the words behind the sofa so the middle of them is ~64" from the floor.

Just because you have a tall wall/ceiling does not mean you have to fill it up to the ceiling. Your proportions of vision are the same. Your words have gotten lost in the dimensions.

Or you could find a very tall large piece of art to fill in the space behind the sofa if you want to fill it.

NO. Repeat.........NO. WOOD.

A larger console, everything else on the wall? OUT Center the console. Lose the stuff on top pf the console. Lose the ladder. Corner arrangement in vase. goes out too. You need not fill every inch of wall or empty space.

It's just clutter fill . Think bigger and LESS.
