Actually i worry that in 3840*2160 30hz mode the output bandwith is insufficient.it may lead to the 4:2:0 conversion to 4:4:4 failure.
In my memory 3840*2160 30hz is only suitable for HDMI 1.4 output port.
HDMI 1.4 output port only transports 4K video with 4:2:0,not 4k video with 4:4:4

that's part of the GPU not madVR.
and no HDMI 1.4 can do RGB UHD at UHD.
why do you even care you are clearly using hdmi 2.0.

a 1000 nit HDR image on a 1000 nit display will have the same image between a HDR signal with 1000 nits and an SDR image properly converted from the HDR image.
gamma, PQ and HLG are just different ways to store the data.
the banding part is a myths a proper dithered image will not show banding. banding is usually produce by the flawed image processing of TVs or other panel related things.
when switching between modes on a TV the transistor to power the pixel will not magical be able to produce PQ from gamma or closer to gamma response.
