I just completed a bunch more tests.
I'm wrong about the dithering being the cause of the remaining banding I'm seeing in 16-235 mode. I took a series of screenshots, and the screenshots (and dithering) applied in 0-255 + Kodi Full + TV Full (which shows no banding), is identical to the screenshot I get from 16-235 + Kodi Full + TV Limited. So, I think the banding is being introduced further down the line - perhaps by the video driver? It could be the TV, but it's extracting the same color region in both examples, so I don't think that's it.
Ideal modes:
0-255 + Kodi Full + TV Full + Dithering On = perfectly smooth but heavily dithered image
0-255 + Kodi Limited + TV Limited + Dithering On or Off = perfectly smooth image*
* I cannot see any visual difference between dithering on or off, however the non-dithered screenshot is 27kb, and the dithered screenshot is 33kb, so something is happening. Also, the heavily dithered screenshot is 494kb, so you can see how much it's doing. I think if there's going to be any actual difference made to a bad rip, you're going to have to be in 0-255/Full/Full mode, since that's already heavily processed all around.
