Wow... there is so much to unpack here.
I'm not sure anyone can help you since you seem to be looking for something that most here would consider wrong.
I can say with a certainty that madVR is one of the best (if not THE best) renderer for it's ability to produce an amazing image in terms of both quality and accuracy.
I can only guess, but either your entire setup has some serious flaws or you are chasing dragons that nearly everyone here would avoid at all costs.
