Is this screen defective?

Hi,

I purchased an iPad 4 recently and when viewing the screen I can see two thin rectangular areas of white light bleeding through under the top bar, one in the very top-left corner and one three quarters of the way along. Is this screen defective?

The iPad seems to work, and the screen itself displays ok, but the lights are distracting, especially when viewing the screen at an angle, such as when it used on a flat table etc (and especially when the screen is darker).

Here's a picture: https://preview.ibb.co/hkEbXw/IMG_0395.j...

Thanks in advance.
