If it's truly Z on KE, then you will earn absolutely nothing. Any fare codes not specifically mentioned on the fare chart earn zero MQM, MQD, RDM
When you used a GUC they flights change from DL coded to operating airline code.
Technically you only are supposed to earn based on what you paid. However if the fare class is an earning one you end up due to system issue earning based on the upgraded flight. Since Z doesn't earn you'll end up needing to request credit manually. Thus likely will earn as you technically should based on the un-upgraded flights.
