You're not seeing anything because the facial mocap solutions are extremely widespread. Back in the 90's I remember software like Softimage's Face Robot having wide use at animation studios and that procedural softbody style being used because it allowed easy transitions between mocap, animator, and procedural controls. About 15 years ago FaceShift was the inspiration for many VFX houses to start their own ML groups to produce facial capture pipelines. The human face has had the most attention, and due to that the in-house facial animation pipelines are very hard to duplicate as commercial products - they are quite sophisticated, with reasons that make less sophisticated methods look pale where it matters: in the facial performance.
