Yeah, I realize that but it's more about the feeling you get from it - just like this whole thing isn't really about restoring the true original, because that just not possible using those means, but to make the viewer feel like they're watching the original as much as possible. Plus it is hardly adding them in the middle of the 35mm frame, more like 1% from where they were originally. Also, another thing I noticed is that cinema screens very often have rounded corners, so this is also meant to kind of simulate that.

If it's about simulating the cinema experience of the original then what are your feelings on adding some grain to compensate for the DNR'd look of the BD source footage?

Yes, we all know that adding fake grain technically destroys detail but not only can it trick the eye into perceiving a more detailed image, would it not be a closer simulation of the 1980 cinema experience than the BD footage as it stands?
