Toyota sent out a bulletin a few years ago that said when a customer complained about excessive smoke the first thing to do was to rev it about 20 times from idle to near max revs (parked and in neutral) to blow out any accumulated soot in the exhaust system & then check how much smoke it was blowing

Costs nothing to do and worth a try to see if it makes any difference
