Actually you will. I wrote a menu subsystem for a game I was working on
that did the Final Fantasy VII-style fade from one side of the menu rect to
the other using a precalculated color ramp. In 32-bit it was perfectly 
smooth,
but in 16-bit it looked like stripes. I added some code for such video modes
that randomized the edges and it looked a bit better (I didn't know how to
implement true dithering :P ).
