Its normal to an extent. Its something that most people won't ever notice. You shouldn't even be able to see it when you're looking for it with the kindle more than a foot away from your face.
This is a picture of my dxg using a barely decent webcam and a 45x pocket microscope, so the quality is pretty bad. Those speckles on the picture isn't fuzz from the picture getting taken. They're actually there on the screen. This is my home screen and I've refreshed it several times before taking this picture. Those dots don't move. I tried to include some font on it to show how close you have to be to see it. The speckles can be bigger than this.
The lower left dot shows up the clearest on here. Just in case someone couldn't find it.
