Jumping back to an old topic, I confirmed the strange features in the screen are definitely not part of the image because they have depth. They are behind the image. You can move your head to see how they move relative to the image on the screen. Unless Tesla put in a 3d screen for some reason and didn't tell us... Not likely, I'd guess.
The only explanation I can think of is that maybe it's an OLED screen and they somehow have control over both transparency and brightness of each pixel? So, light colors are highly transparent, but if the brightness isn't very high, you can see through the screen?
Just a really strange design choice. I can't see why they would have picked this panel or installed it they way they did to cause this artifact.
