This is Pretty Neat. Unfortunately, since the Sony IMX377 and other 1/2.3" sensors, most smartphone sensors have abandoned 12-bit, for photo or video (Staggered HDR sensors do 12-bit HDR for photos instead). So, this is limited to 10-bit video for now. But, the video quality looks pretty stellar. Unprocessed and I am guessing the highlight and shadow recovery maybe pretty decent. It apparently does 10-bit 4-2-2 (most smartphones that do 10-bit video, have 4-2-0).
(The new Snapdragon and MediaTek SoCs talk about 18-bit imaging, which I am guessing may be some crazy HDR, upressing bit-depth, though that may solely be limited to photos).
This RAW video does look pretty neat, and doesn't look over sharpened or over processed like most smartphone footage.
