Uhhhh...
Do you have a bright light shining behind the screen or is the back of the display facing the setting sun? Sure looks like the Apple logo.
In fact, I can mimic exactly what you're seeing by holding a flashlight up to the logo on the back of the screen as long as I have light/white colored pictures or windows open. Opening a large black window blocks the light.
Is it "normal"? No, I wouldn't say having a blinding light shining at the back of your display is normal.

The display panel itself showing the light, however, is normal. It doesn't care where the light comes from, the backlight is just that, it also illuminates the Apple logo. It's not inconceivable that the opposite would happen should the light behind the laptop be brighter than the backlight itself.
As such, no, I don't think your laptop has a problem.
