There are two ways to reduce colour banding in POV-RAY

1. 16-bit depth to have a more accurate spectrum of colours.

2. Dither to fake the colour gradient.

Unfortunately, neither of these methods is available if the output format is
JPG.

If we output a PNG file with +TH, and then, convert it to JPG, the colour
banding disappears.

I wonder why can't we directly save the same effect with JPG output.
