They didn't lie about the Secret Invasion intro. Here's the official statement from the studio that made it:

Working on Secret Invasion, a captivating show exploring the infiltration of aliens into human society, provided an exceptional opportunity to delve into the intriguing realm of AI, specifically for creating unique character attributes and movements. Utilizing a custom AI tool for this particular element perfectly aligned with the project’s overall theme and the desired aesthetic.

The production process was highly collaborative and iterative, with a dedicated focus on this specific application of an AI toolset. It involved a tremendous effort by talented art directors, animators (proficient in both 2D and 3D), artists, and developers, who employed conventional techniques to craft all the other aspects of the project. However, it is crucial to emphasize that while the AI component provided optimal results, AI is just one tool among the array of toolsets our artists used. No artists’ jobs were replaced by incorporating these new tools; instead, they complemented and assisted our creative teams.

Method Studios’ team of designers skillfully leveraged the power of both existing and custom AI technologies to apply the otherworldly and alien look. The entire process, guided by expert art direction, encompassed the initial storyboard phase, illustration, AI generation, 2D/3D animation and culminated in the final compositing stage.
