On what display are you viewing these images? Your gradients only use a
small subset of the RGB color-space (about a few dozen colors). Most
modern displays are not able to render all the 16 million colors of the
24bit RGB color-space. Modern LCD panels, unless you spend a lot of
money, are limited to somewhat like 20 or 18 bits. So that will further
reduce the amount of colors used to display your gradients.

If you enable dithering and look at the results on a good monitor,
favorably a well-calibrated CRT, then the gradients should appear
reasonably smooth.
