That's likely a wrap as there's no paint on offer from Tesla and a clear vinyl wrap is available for I think 3k. This black wrap was likely done at a third party shop. Probably cost around a 300 to a grand depending.
I played a lot of N64 so the aesthetic is nostalgic. Unfortunately for Tesla, I don't have enough money to buy a video game accessory at their price. For what they're asking I'd need it to be an actual vehicle with the capability to survive a light rain.
It's not an option from the factory, it's an aftermarket wrap. I have seen a few already on the road that have been wrapped in black. Does look better than the raw metal, but doesn't make the driver look any less like a tool for driving a cybertruk,
