It's called a stuck dead pixel. A white one which constantly emmits light is certainly more annyoing that a dead black pixel.
I have not seen one on my GoPro cameras so it not normal. Depending on GoPros production tollerances it might be acceptable for them but not for you.
Try to get a replacement camera if you can't live with it.
