That's a philosophical question based on whether you hold a descriptive few of language or not.
"Creative" as a noun meaning content shown in a single advertisement with the plural of "creatives" is definitely in use in the places I've worked, which include a magazine/traditional publisher and a silicon valley tech company that has a large market share of the advertising industry.

thanks - I would say the wiktionary entry probably needs updating in that case.
But below in this thread I asked for example usages and the person I asked said:
>"We have to work on the creatives to show to the client next week."
That does not match the definition you just linked.
https://en.m.wiktionary.org/wiki/creative#Noun
it says "creatives" are people "some of the creative" (and the like) would be the things. It explicitly calls it uncountable in that definition. So does the wiktionary entry need expnasion, or was the example usage I received, wrong?
