You could probably tell if that is true, by checking the diameter of two different brands that are IGFA certified & of the same pound test. Their pound test rating should be the same, shouldn't they ?? Of course, they'd have to be the exact same "type" of line. You couldn't measure copoly against copoly coated fluorocarbon, or even regular fluorocarbon, or any of those against straight monofilament.
