The answer for OWE is No because OWEs are not entitled to upgrades on AA. AA EXP’s do get day-of upgrades to PE on international flights if seats remain. I don’t know about Alaska - AS 100Ks may get the same, as they do get the equivalent of SWUs.
Regardless, it is never instant. Only day of flight.
