There is! You can negotiate a lower salary and higher participation. Obviously they have to want you, but when a show like this is starting up and not at all sure to even make it one season, an art director who would work for 25% pay and 1% of future profits would be snapped up.
The way around Hollywood accounting is to negotiate points on gross revenue or royalties rather than profit. That’s SOP in TV/movies for people with decent representation and the leverage to ask for it. Points on profit are largely seen the same way tech people view startup options.
