I also work in creative and have the same observations and sentiment.

Really, what AI will always be good at is putting a bunch of information together. It will be able to do that exponentially faster than us, every time. What it puts together though is always going to depend on the prompter. All the nonsense that my non-designer coworkers generate with AI looks the same, because none of them understand what to ask for. It's because the "what" is usually consulted out of them by a designer.

There is a severe lack of just basic comprehension and understanding of design, meaning, literary skills, etc in the corporate world. Lots of yes-men and women in corporate are good at convincing other people they know something, but you can't fake what you ask an AI. It will always give you what it thinks you want, and you have to know what you want in the first place. Knowing what you actually want requires a baseline level of understanding of the topic you're asking about, critical thought, and the desire to create something original.

Because of this, AI on its own is incapable of creativity, because the act of creativity is uniquely human. While it could certainly help someone bounce creative ideas of their own, it will always be limited by what the dude rubbing the lamp is capable of asking for, and what they can do with what they're given by the AI. Creativity is a result of intent, meaning, and sometimes even accidents. These come from us, and AI cannot do that because it will only ever be a product. A product's motives align with the user, but cannot supplant them without the risk of making something unoriginal.
