Does Sony Bravia 2 M 2 K-55S25M2 don't have backlight bleeding?

I've decided to either go with Lg qned 82bxa or Sony Bravia 2 mark 2. Almost everyone here has watched our admin's tv and he compared it with other TVs as well and I did notice backlight bleeding and edge glow.

I did my research and got to know that there are actually two Bravia 2 mark 2 TVs, one is K-55S25M2 and the other is K-55S25BM2. Some ppl say that the K-55S25BM2 has backlight bleeding but not the k-55S25M2, and that, it's also more expensive than BM2.

Can anyone confirm it? Please let me know cz sony is sony, if I don't have backlight bleeding and edge glow in K-55S25M2 model then I'll go for it man.
