In the end this is a matter of opinion and taste I guess but do expect to see stuff that was never intended to be seen that's visible on the O-neg but was never visible on prints. This is something studios recently have realized when releasing some of their classic catalog titles, where they instead aim for something that is more representative of what would have been seen in theaters instead.

Generational detail loss is fairly easy for the end-user to simulate. If I'm ever watching a movie that appears too sharp, I can switch my player's output to 720p or even 480p. That blurs up the picture pretty nicely--not necessarily to EXACTLY the same level as theatrical prints of that particular film, but pretty close.

There are some advantages to going back to sources earlier than projection prints other than more detail. Assuming nothing else goes awry with the Blu-ray, I think OCN-based transfers are usually a good choice for the studios (but there are always exceptions). It's much easier for the end-user to "fix" a too-detailed Blu-ray than a wrong-colored/DNR'd Blu-ray.
