There are three places where conversions can happen before the display and they do not interact. The display can be doing conversions internally too, but we cannot control these.

1) LAV video can do a conversion if the render does not support the source format. When using madVR this should never be needed and it is not ideal.
2) madVR will output RGB at whatever bitdepth is set.
3) The GPU driver will do a conversion to whatever you set in its control panel.

madVR will never change what it outputs based on what the GPU is set to and the GPU will never change its output based on what madVR sends it. All these steps simply convert any input to their configured output format without a lot of smarts involved. For example the GPU is happy to convert madVR's 8 bit output to 10 bit. You know for sure what the GPU is outputting based on what it is set to in its drivers.

Also, I can send my TV 8 bit RGB HDR and it will say HDR10, that is just a brand label for the metadata standard, it works with 8 bit RGB too.
