This also improves the noise floor, because something happens/changes in the A/D conversion at +9,3db. You can clearly hear it when slowly turning the global input gain up step by step. Therefore I have my global input gain at +9,3db and the gain on my input blocks at -9,3db. But that doesn’t falsify the above argument of the blocks behaving the most realistic when they see a overall gain of ±0,0db - because that holds true here (+9,3-9,3=0)
