I can only go on what the dealer told me, but they said it was dirty. It doesn't sound to me like this is a common problem or that there is a reason it should be dirty. That's the information I am looking for.
Not sure how much they can tell from the inpection; usually it's just sticking in a finger to see that the level is up. That being said, I have had a transmission/differential where I checked at 5,000 miles and the lube was VERY silvery and I replaced it long before the maintenance interval, which was 30,000 miles iirc. Now, did it make any difference? I don't know. Probably had no practical effect. There's probably a certain amount of wear metals to be expected during the first few thousand miles. Eventually those particles become captured by the magnetic drain plug.
Changing it once prophylactically might have some logic if you're the type that wants to know that the lube is PRISTINE and free from those initial-wear metals. But I call BS on a second time. If something is wrong a second time then the unit has a mechanical fault that should have been investigated. The dealership is probably one of those who are disgruntled at the low rate of maintenance and repairs for the LEAF and looking for some extra play.
