Prior to 4.0.0 there was a default of 1.0 for all physical pixel sizes
if they were not provided. In 4.0.0, physical pixel sizes are optional
so assuming you imported the file using 4.0.0 clients and server I'd say
the values you're seeing are definitely from the file.

The intention of the dialog historically was to provide a way for the
user to override the default metadata population (ie. 1.0) for a
singular import and not to override the metadata in the original file.
Since these fields are now optional the dialog's intent is still valid.
I'm not sure about overriding the metadata in the original file... gets
us into some muddy water rather quickly.

Thoughts?
