It's doubtful the packaging had any effect at all on the yellowing. All
ABS LEGO bricks, white or otherwise colored, should yellow eventually,
simply because of the heat-molding process used to make them. That
initial heating process obliterates a certain amount of hydrogen atoms
in the ABS, leaving open carbon bonds exposed on the surface to attract
whatever sort of atoms happen to be floating by. UV exposure from
sunlight merely accelerates an inevitable process. Unless they started
sealing LEGO in airtight argon-filled polybags, and packaged them in
UV-blocking boxes, the parts would still yellow, in the box or otherwise.
