If anybody has TERRIBLE banding in dark tones, try installing the latest graphics driver from NVIDIA website. Today I formatted my PC, and I was using Windows Update graphics driver, which works fine for most things, until I noticed this terrible banding in dark tones after using novideo_srgb (even when I had dithering enabled, it didn't work). Installing the drivers from NVIDIA website fixed the issue.
