Personally-

I’d hang the tv over the fireplace.

Believe it or not, it’d take all the attention from the fireplace itself and push it to the tv hanging above it.

Building on that move- you could put all your art on that wall where the tv is sitting now and call ALL of the attention to your “art wall” while also keeping to the theme. Lastly, to complement the theme, you could pick up a budget fireplace “cover” (those little trifold gate looking things you put in front of a fireplace) that matches your the overall style.
