Pretty sure most film stock works the same way: three separate layers, one each for R, G, and B (or C, Y and M). So, no, there's no separate chroma and luma in film.

Chroma and Luma are technically digital video terms. 35mm Kodak negative stock has three layers of colours, RGB, which record the respective information of those spectrums.
Seperation masters are three black and white masters made from each colour value. One is a record of all the red value information, the other the green and the other the blue. The combined master of these three colour sepation records would theoretically give you a perfect replica of the original. George Lucas had these made for Star Wars, although I'm not sure about the two sequels.
