While Karl was a little strong in his reply, read what he said: As long as there
is flow, there is lubrication.
Cold starts are damaging because parts which have been drained of oil are made to
turn without lubrication. My bet is that an equivalently drained engine with
warmed-up in the oil sump would show almost as much damage as one with totally
cold oil (all other things equal, the warm oil should flow better and thus
lubricate the dry bearing surfaces quicker).
The implication otherwise is that room temperature oil does not lubricate, which
counters observation.
