Comment (by Balling):

 So for DV it should also be AVCHROMA_LOC_TOPLEFT.

 Also


 {{{
 case 4:     // MFVideoTransferMatrix_BT2020_10
  ret = AVCOL_SPC_BT2020_NCL;
                 break;
 case 5:     // MFVideoTransferMatrix_BT2020_12
  ret = AVCOL_SPC_BT2020_NCL;
                 break;
 }}}
 If MFVideoTransFunc_2020_const is not applied, if it it is CL.

 That ITU signals CL in matrix, while crazy Micro in Transfer. Well...
