Here's another observation to show how the relationship of a constantly changing black point within the process to final viewing pipeline that requires scaling to overall shadow densities.
Below is a shot of a mural and an inset shot 2 hours later of a section in shadow. It is a depiction of a night scene. The muralist didn't use absolute black paint to draw in the cracks of the rocks because of the extreme viewing light variances that would force the rocks to scale too dark for each extreme lighting conditions and to prevent the darker black cracks from looking posterized as I've shown by drawing in 0,0,0 black dashes.
Not saying you need to make your edits this light in the shadows. This is just a demonstration of an optical phenomenon regarding perception influenced by variances in black densities and how they relate to variances in dynamic range and light levels. Your transmissive display and your digital images of real scenes have a far bigger DR than that mural even when the mural is lit by bright sunlight, but a print has far less than the display but more than the mural due to both the lighting it's subjected to and the density of ink and obsorption=reflectance characteristics provided by the paper.
The black of a transmissive display has an infinite density, a black hole with regard to human perception, where as a print's black density is not, even though you think the black looks the same as the display's. It isn't especially under varying light levels.
