I would not -- but then I'm a "don't paint the brick" person -- I think it's a great focal point.

I like the brick, but it would probably look nice painted, too. Someone on these forums painted her full brick fireplace wall black and it looked terrific.(I'll see if I can find the thread). And, frankly, I think that enormous tv is going to be the focal point regardless of what you do to the brick, but a dark paint color might lessen the tv's big, black dark hole impact a bit because it would blend a bit more than it does with the red brick.

eta: here is catmom's black fireplace wall and a link to her before/after thread:

Thanks for posting my thread/pics Olychick!

Grace’s bricks look nicer than ours did (lighter, less red?), but they/the wall would also look good painted.

As much as I like painted brick, I'm not sure you should do it....yet. The first thing I would do is work on your furniture arrangement. Is that the only spot for the tv? I'd want all of the wires and components in a cabinet. Make a scale drawing of your space BEFORE you go furniture shopping. A light colored rug could help brighten up what appears to be a very dark space.

I'm glad you were ok with it catmom...I wasn't sure you were still around to do it yourself!
