I don't get that impression from the image for two reasons: (1) printers don't have blocks of red separated from green and blue (the left side) and (2) I know of no display that represents a pixel with an L shape (the right side).

That said, it might be good to move away from R, G, and B (toward basically any other color except white) to avoid potential confusion between "3 boxes of color" and "sub-pixel slots for R, G, and B".
