Sorry for replying late. I didn't see this post. Well, I just turned off every light in the room, including cell phones, and covered the LEDs on the laptop. Now, I noticed that there really is some bleeding from the logo. It is there on the bottom right corner, but it is so faint, that it is almost unrecognizable. And, it is to be expected as the logo lights up the screen from the behind. However, it should not be a problem, as the screen itself is LED backlit.
On a serious note, I don't think it is a matter of concern. I didn't even bother to read the forums where it was discussed. If it was harmful to the screen, no company would put it there. Even MacBooks have a shining apple logo on the back of the screen.
Again, sorry for wrong information that I provided earlier, but it is so faint, that I missed it. It is only visible in pitch black, and if I take a pic of it, it comes totally dark.
