ECS is more about shared components and batched processing of components, than it is about instanced rendering. You can instance render with or without an ECS quite easily, and an ECS doesn't negate a scene graph. Often you'll have a scene graph and an ECS. The scenegraph consists of the entities. Otherwise it can get difficult to do a lot of world scale processing like loading in segments etc..
