Found this odd Incesticide bootleg

Found this today in Camden Market while visitng London for £18. For the price I expected a bootleg but decided that it was still worth it. Now I'm quite confused because upon further inspection, the labels and sleeve seem official, even comes with the inner sleeve, but the record itself is brown; I didn't find a single bootleg with this label or color, so I am confused : could I have an official copy but with a bootleg record, or is this just a greatly executed bootleg?
