But to be fair, when you look at a B&W photo, there's no argument over what you're seeing. OK, maybe its grayscale, but you're not seeing color that's not there.
Here, on the other hand, there's no unambiguous "this is 8-bit" message coming through. Seeing the clip and none of the associated description, I'd probably assume it was supposed to imitate a 16-bit game, just based on the color palette, colors-per-sprite, and all that. Only the bowling game sequence looks 8-bit.
