Incorrect. Since the rules are silent on the matter, the default situation applies, which is that ethereal creatures are just as affected by invisibility as anyone else. The rule, essentially, is that there are no special exceptions for ethereal creatures.
Your argument isn't much different to saying that just because there are no special rules for how orcs take damage, that means the DM can make up stuff to fill the gap. No special rules are given for how orcs take damage, because no special rules are needed: they take damage just like everyone else.
Actually, as Olgar says above, the rules are not silent; they are vague on this particular issue. The relevant section in the Manual of the Planes, pp. 55-56, can be interpreted a couple of different ways. No, it's not a Core Book, but it comes the closest of any WotC book I know of to the subject.
