A P&S version does not "open up" the image. P&S, short for Pan & Scan,
refers to a specific process where the image is cropped horizontally and
scanned, with the scanner panning across the image to keep the most
important elements in the frame.
The process you're referring to is "open matte," which is another way to
create a 4:3 image from an originally WS image. In this instance, the WS
image was originally created by cropping, or "matting," the image
vertically from an exposed frame of film that was 4:3 or 16:9 in aspect
ratio. In "open matte," the original matting or cropping is either
eliminated or reduced.
Some films use a combination of both methods above to create the 4:3 image.
So since a 4:3 version of a WS film can be created via multiple methods, as
well as multiple combinations of the methods over the course of the film, I
typically refer to them just as 4:3 to avoid confusion.

Well, since more image is visible, it'd make sense that the grain would be
seen in the additional image as well, making "more grain" in the image. I
don't see how that would create a noticeably grainier image though.

Grain is an element of film, and sometimes a very desired element that
cinematographers and directors may aspire to achieve. Before they try and
reduce the grain on a film, the technicians should check to find out
exactly how much grain the director intended the film to have.
