Is one of your arguments then that 8bit sound or 8bit video has more dynamic range than something else with more bits?

No. Where did I say that?

Well certainly that is possible, with bad design considerations or components.

Why are TV manufacturers all about HDR10 now? because there is banding in the sky of a video. Does that mean that tonality is less with HDR10... nope. HDR10 helps limit this but I haven't seen it to know.

Obviously you need a 10bit output of video for HDR10 to work, give it something less and you will still get banding in the sky.

More A/D conversion bits always has the potential for more fidelity in signal rendering. That ultimately becomes tonality etc when done right.

If you have a 14-bit ADC outputting to a 10-bit medium, you are quantising the signal. You get worse quantisation with 8-bit obviously.

Nothing to do with DR, but a lot to do with the number of reproducable colours or shades - hence banding on 8-bit displays.

Most sensors don't have enough noise to dither banding on 8-bit displays, but they do on 10-bit devices. Hence the move to 10-bit TV/Video standards.

So going from a 14-bit to a 16-bit ADC on the capture side won't make any difference to the colour depth or tonal depth of the image.

And it's unlikely to affect the dynamic range either.
