New lg g2 out of the box faint white lines all over the screen, normal or not ??? topic

I have a lg g2 out of the box faint white lines all over the screen, and i'm wondering is it normal or not ? I read a little today that there a 2 kind of screens out there. One screen is ok and the other has these white lines on it. I'm not sure if this is a defect or not. Some say these white faint lines are actually the digitizer visible on screen befause of the fabrication process. Other say that its kind of a defect and should return the product . My question is what is the truth ? is this a defect ? can it get even bad than faint lines in time ? or they will remain just faint lines ? Its not a deal breaker for me just yet , but if someone tells me that this will get bad bad :) I will return the phone . So please I need some imput
