I am not a mechanical engineer so my guess may be wrong. Having said that, from what you are saying, it seems, when oil is fully warmed up and engine start is initiated oil draining out of hydraulic tensioner is faster then the oil system pressure build up to feed the tensioner. Whereas, when the oil is cold (perhaps due to higher viscosity) oil is being held in the hydraulic tensioner longer and pressure build up is seemless.
I noticed that if I turn the key without starting 2-3 times (did it to intentionally to move the pulleys a bit) when I actually start chain rattle was severe which never happens on daily normal start. I concluded that when I ran the motor w/o starting oil in the tensiners were being drained and w/o actually running were not replenished w/ system pressure. Just my theory.
