I've seen some 1/200 plastic models turn yellow inside display cabinets, without direct sunlight whatsoever, so it is related to the kind of light and the ammount of UV that light source emits. Bare white plastic is more susceptible to discolouration than white paint, but eventually even paint will deteriorate somehow.
I would worry more about rubber parts drying out and cracking than about yellowing plastic.
