3 x 3 is a waste. You only need 3 x 1 or 2 x2 for colour. How the pixels are arranged makes no difference to the 4096.
Pure black and white pixels allows White, Black, 3 primary and 3 secondary colours on 3 x 1. Maybe three more on 2 x 2 as you can have 1 x R or 1 x B and 2 x G, or 1 x G (a greenish Cyan, a greenish Yellow and half brightness green). I agree that the 3 x 3 cell would increase the range of colours with pure black/white, but it would still be harsh and still very few shades.
