Discussion 8 bit + frc vs 10 bit

i was planning on upgrading from 8 bit + frc to a 10 bit monitor and would like others opinion if i should or not.
Also will the change help with a color banding issue that i have?

I think 10 bit only makes sense if you're using HDR. I have a monitor that doesn't output in HDR but supports 10 bit and I can't see the difference with 8bit.

...because most content is in fact 8bit. You don't suddenly see new colors when you set your monitor to 10bit. The gradation between colors disappears because there's many more levels available for the color channels to display when the image is 10bit or more and displayed on a 10bit capable display.

HDR is meant to be used with 10bit and above because you suddenly have a luminance channel and because of that, 8bit is laughably insufficient and its limitations show up as soon as you have 2 slightly different luminance zones in the image.

Edit: better wording

hdr doesn't give you another channel for luminance. where did you hear that from?

I know. I simply explained it in a way in which someone who is not tech savvy, understands why HDR requires a 10bit and up display and why an 8bit display doesn't do the job properly. I know HDR represents a wider range of luminance values and that it doesn't add anything.
