What makes you think it's WebGL? It looks like an mp4 to me, at least I was able to download the mp4. It's sharp because it's high resolution.

But maybe they're serving different content depending on the client.

You’re right - I confidently asserted an assumption and turned out to be totally wrong.

I had no idea videos on mobile sites could look that sharp and well integrated… I guess I’m used to seeing them done so badly this one stuck out, so I thought it had to be WebGL

I’m a subscriber with the mobile app and the “video” is a still image for me.
