So, offsetted to the real display black level ideal curve, is used as
target for all input levels except near 50% , where original ideal curve
used instead? And this helpful in my case, because displays have different
black levels?

I try raise black level of one display only by the LUT manipulation. That
new black level will be used for target curve offsetting or only initial
display black level?
