There is loads of wiggle room in the T&Cs when you buy a car.

I went through all this many years ago with Vauxhall VXR and their Stainless Steel Pedals that just weren't a thing outside of the

I've looked at ours, and it definitely is some sort of "moulded thing".
There could be a bit of dead cow in the moulding, but it's clearly not leather in the generally accepted use of the word.
