i'd say it depends on where you're applying and for which position. if it's some super snobbish ad agency that takes industry awards way too seriously and you apply for a senior art director position, i definitely wouldn't include that. If it's a bread and butter type of gig, that's a totally different story, and if you're applying for some in-house marketing position, they probably won't mind, either. If it's a specialized retouching gig where you're mostly doing the final stages of an artwork, i absolutely would include it, too.

pls note that i'm not a graphic designer, haven't worked in advertising for a while and have no idea what the market in other countries looks like, or what advertisers and marketers think of dall-e, as i haven't talked about that issue with anybody from the industry that i know. i'm not completely talking out of my ass here, but i'm mostly guessing.
