For batch rendering, it doesn't really need to be efficient though.

 
Of course it does. Ray-traced renderers can compute hundreds or
thousands of rays per pixel, taking anywhere from minutes to hours per
frame. This is how you produce those cinema-quality 4K (or even 8K)
frames. Anything that can shave a little bit off the time for a single
ray computation can very quickly add up.
 

You don't do raytracing in OpenGL...
 
That is not the point of using it.

Precisely what I have been trying to say.

Similarly, not everything needs raytracing.
For many uses, rasterization is fine.

There are renderers that are based on video-game engines. And they can
indeed use GPU-based compute APIs, as I mentioned previously. But they
still don’t use OpenGL for rendering.

For a lot of shows, you don't even really need 3D.

Funny, that. It is quite common to create 2D-style animations with 3D
software nowadays.

One might instead go the other direction, and use a 3D renderer with a
cel-shading filter to try to make it fit better with the anime
characters ...

It takes a bit more than cel-shading to get a good 2D look with 3D
software.
