arturpanteleev Banding does not prove or disprove the presence of FRC / Temporal Dither.
Banding is just what occurs when a gradient within an image of higher bit depth than the screen it is displayed on is present.
FRC usually gives you 2 more bits.
Gradient on 8 bit image displayed on true 6 bit screen -> Banding
Gradient on 8 bit image displayed on true 8 bit screen -> No Banding
Gradient on 8 bit image displayed on 6 bit + FRC screen -> No banding
Gradient on 10 bit image displayed on true 8 bit screen -> Banding
Gradient on 10 bit image displayed on 8 bit + FRC screen -> No Banding
Gradient on 10 bit image displayed on true 6 bit screen -> Strong Banding
As long as the monitors bit depth is somehow the same or higher than an image displayed you will not see banding (some exceptions like compression artifacts excluded)
More color depth is not bad for flicker sensitive people, there is just a problem if some of that color depth is achieved through flickering (FRC).
Btw those bits are measured per color. Red, Green and Blue each have 6/8/10 or 12 bits for themselves.
There is an old color standard that mapped colors per pixel. With this old standard a "8 bit" monitor would only be able to display 256 colors per pixel.
Modern monitors, images and color depth standards like HDR when they say 8 bit color depth mean in truth 8 bits for red + 8 bits for green + 8 bits for blue.
A modern 8 bit screen can display 16.7 million colors per pixel.
