> a whole bunch can be lost when transferred to optical print
I’m not sure if by "optical print"[0] you mean a film developing process (like C41), but the info is not lost and stays on the film. The developer job is to fine tune the parameters to print the infos you’re seeking, and that include adjusting white and black points thresholds (range). You can also do several print if you want to extract more infos, and print it so large you see the grain shapes! If there’s is something lost it’s when the picture is taken, after that it’s up to you to exploit it the way you need.
It’s very similar to a numeric device capturing RAWs and the developer finishing the picture on a software like Camera Raw, or what some modern phone does automatically for you.
0 not English native, perhaps this is a synonym of developement?

You have a negative, which you develop.
For photos you then have to transfer that to paper. For cinema you want to distribute it, so you have to take the originally captured image(s) and make copies to distribute.
In both cases, because it's an analog process, and so things will degrade.
Of course if you scan the negative then further copies after are easy to duplicate.
