Yes, that is true - you can get one from the LFA now. It hasn't always been the case. They must have changed that in a patch without telling.
It's still called "Matt Black", without an "e", but it is exactly the same colour as "Matte Black". The miniature pictures of the paints show, that "Matt Black" should be a tiny bit darker than "Matte Black", but when you put it on your car it isn't.
