New Grey Apple Boot Screens?

Your vision is dynamic and adjusts itself to the overall lighting, it was probably just the lighting in the room (the brighter a room is the dimmer a Backlit display will appear).

I've had that screen pop up a few times after my computer crashes. It'll do that for a day or so then go back to the light grey version of the boot screen. I'm thinking there's something in correlation to my computer randomly crashing and that dark grey boot screen.

Looks a little more textured, but the colour seems the same to me.

The screen is normal the dark grey screen with the black apple only shows up once in awhile. Like I said after it restarted on its own one day it turned back on with the dark grey with the black apple as opposed to the normal boot screen
