In scanning ads for HP calculators, I have noticed a couple of photos that show significant darkening of the pixels. It looks like every pixel and annunciator in the display is half-darkened even when they are not active. I'm wondering if this is real burn-in, or just an artifact of the camera flash going twice through layers of the LCD as it reflects back at some angles.
Here's an example:
