This looks right, see

It is 4:4:4(:4). But I am not a guru in this))

Resolution: invalid
Status: newclosed
Version: 4.1.4unspecified

The linked MS documentation clearly describes a 4:4:4:4 format.

Ok, thanks. I guess its an error on the MS site then, that it says:

4:4:4 Formats, 32 Bits per Pixel

A single 4:4:4 format is recommended, with the FOURCC code AYUV.
