So apparently the volume is loaded in 3 chunks 95MB (285M). Looking at the code they are indeed using WebGL (through Three.js) for the raytracing. I don't think it's a DICOM format, at least not on the frontend side as I don't see the usual DICOM fields used in 3D rendering in the code. They have multiple versions of React bundled, I don't know what's the story about that. Anyway, thanks for the link, nice piece of technology.
