What dohraime said.
Everyone here knows my aversion to grey so don't tell anyone I said so, but I think a deep grey wall could look good too - something the TV could disappear into. There are paints now with like a suede finish if you wanted to add some extra interest, or do you know you can get paintable wallpapers. Bunnings have them but probably other places do too. They are an embossed paper you just paint over.
You could also put a series of black and white photographs across the wall to detract from the TV too.
If you love the look, why not. Especially given wallpaper is non permanent. My concern would be the pattern could be distracting when you are watching tv...
What type of brick look are you thinking of? The whitewashed look, distressed red brick?
The wood wallpapers could bring in industrial look also. Something in the grey tones to tie in with your sheers perhaps?

My brother-in-law runs a online photo slide show on the tv when they aren't watching programs. Beautiful photography from around the world. Much more interesting to look at the the black rectangle.
