Bias Lighting Question

[DIGITALBATH]

So, in my reading about bias lighting I learned that it is best to have a white, or light colored background behind your TV, well I live in an apartment and it is more like a wood paneling, so I'm out of luck there.

I decided to go budget and picked up a 60 watt replacement 6500k bulb to go with a lamp that you clamp onto, whatever you want. So I have the lamp shining at the wall, and my ceilings are painted white, the light shines about 15-20 inches on the ceiling. Is this a bad thing? I do like the effect, but I wish I simply had a white wall. The fact that it splays out beyond the TV, kind of bothers me, though it is easier on the eyes. Any thoughts?
