Land of the Lustrous... Aaaaand... That's it. And that's a show that's watchable ONLY because it's the only show that does 3D-CG-as-2D somewhat decently as a case study, it doesn't really have any other merits.
It CAN be done... But... That anime is years old now, and they've not reached that level of approaching-decent CG animation since, so clearly it is too costly or difficult to do. And they did every cheat in the book: The villains are non-Euclidean, the protagonists are animate stone golems, the scenery has minimal details, they did everything they could cheat at to make it work, and it... approaches decent.
