From my experience yes. However there’s still a huge divide between TV, Film, and Game production. In both Game and TV production, there is very little work done exploring the “style” of the finished work. That’s not to say no style explorations are done, but it’s more like art done with the intention to explore style. It’s a focused step in the process.
Whereas in western animated film, it’s more like stream of consciousness rambling or exploring with no specific end goal in mind.
Miyazaki has a style of his own and his team knows how to translate that to production art. In games, it’s similar in that the style is usually photorealistic renderings, even if the locales and characters are fantastic. In TV, the style is decided beforehand and by the creator. The style of Tron:Uprising was pretty much decided when they hired Alberto Mielgo, for example. Motor City was destined to look the way it was when they hired Robert Valley. They had the style in mind and hired the people who could make it a reality.
Whereas Disney’s Tarzan, Pixar’s The Incredibles, Lilo and Stitch, were decided in the exploratory phases, in the visdev step. They had people and let them play until they found something they converged on.
It’s about the degree of experimentation allowed, and what aspects they’re allowed to experiment on. In that respect, I separate style from content. Location and clothing being examples of content, and line weight, rendering, use of contrast in light, etc being examples of style.
A great example would be Miyazaki vs Takahata. Mononoke vs Kaguya.
