It doesn't, of course. I just prefer to have a more immersive experience with the black display surrounding the "black unless active" display. The white doesn't hinder anything, but I think watching movies and media is a slightly better experience with the black bezel. Like a 9.25/10 to 9.0/10 kind of difference.
Considering that will be my main use i will go to a store an evaluate, you may be right about that.
