I am just speaking from my own observation - We don’t see dark areas like pitch or tar, we see slightly grayish blacks with our eyes. From most 35mm film frame stills I’ve seen, blacks are almost always slightly gray. This keeps the image soothing to the eyes as pitch black feels harsh. This is why I suggested that the black levels be somewhere between the screener and the corrected version. Also, the “darkest blacks” draw too much attention towards those portions. Just my feeling.
