I'm right.

Grainyness results from a feature of the chemical emulsion used in manufacturing film. This feature doesn't occur with charged coupled devices. The feature you see with digital cameras is one of random noise from the signal processing circuity, and shows up as green-and-pink (or some other color) discolorations in the image. The net result is a little different and it isn't called "grainyness".
