If you find some accesspoint hardware you can run from one of your TV location outlets then maybe it doesn't look so bad mounted on the ceiling, depending on whether you have any furniture next to it to distract from the weird cable in the middle of the wall.
Wondering why you would be running an AppleTV over wireless when you have TV ethernet outlets on the wall that could give you Gigabit as well as offloading some traffic from the potentially congested wifi. Are some of your ethernet links faulty? Should be easy to fix.
