Which do you prefer for a fireplace accent wall?

This is in a living / dining room open concept (approx 13 x 27). This is what the dining end of the room will look like (once the chairs are delivered):

Also, I realize the TV above a fireplace is not everyone's preference. The images below are based on:

-58 inches from Center of TV to floor

-Seating is between 8 1/2 and 16 ft from the TV

-Maximum vertical viewing angle (looking up at TV) is 7 degrees (which these seats would rarely be occupied while watching TV).
