I think I saw in a podcast with someone from the anime industry that it is being used for digital animation by some people there. So I definitely believe it is making inroads. NVIDIA has also included it into omniverse as a first class citizen with other more "enterprise" applications. So I would definitely say it has traction.

I do not believe a vast majority of those people are using Linux however, or at least I haven't seen any indication of it. (But maybe some companies render servers do and maybe Blender is useful for that, but like Maya works on Linux iirc)
