You could put 3 different height candles on the left but really nothing is needed. I agree the TV is too high

You do not need a Frame TV to display art as a screen saver. You can down load art to any smart TV to help fill in the black hole from the tv when not watching.

No other spot for the TV? If not, I agree with nothing else on the mantel.

IMO if the TV stays nothing else on the mantel but please at least get a wall mount to be able to lower the TV for better watching height

The tv is mounted on the wall

Right now it is. Is it the only spot it can go? Mounted tvs can have articulating arms that allow them to tilt and turn and be pulled down.

Yes, the tv is mounted

We can all see it is mounted. Do you want help in this space? If so read the questions asked and then take time to answer them to get solutions.

Loads of questions because you did not stand back to take pics so folks can see the entire room.

Start by choosing a focal point, such as a work of art or a feature wall. Arrange seating around it for balance. To create a cozy and inviting space, use layered lighting such as lamps and overhead fixtures, as well as rugs, cushions, and throws.

8 days still no info I guess the issue is solved . We can't even see the whole space so no help .
