Repeated search with one-ways (instead of roundtrips) and was able to find some instances of what superficially look like ITA marketed flights being presented. However, the pricing used in the Calendar view and fare listings actually only quotes the higher priced DL/AF/KL marketed fares on AZ metal (with DL/AF/KL filter set) and not the lower price AZ marketed fares (which only appear as an option after you have selected their flights.). So this is still an effective means of filtering out the lower priced AZ marketed pricing options which don't earn anything in the Calendar view pricing displays. You can potentially see some dates with AF/KL marketed AZ options as lowest price option (which wouldn't earn), but this looks to be pretty rare. Notice how exact same 10:50PM AZ flight below shows as $643 (which is the DL marketed price) with individual carriers selected vs. $519 (AZ marketed price) with just Skyteam selected below.
