Dolby Vision is internally 12-bit, and does tricks with dual layers or a non-backwards compatible base layer and metadata to reconstruct the video in an internal 12-bit format. If we had 12-bit decoders when DoVi was coming out, we'd probably just have a HDR-12 base layer + metadata.

Only current use of 12-bit for anything I can think of is in intermediate post production or high end mezzanine formats like J2K IMF.
