Ryzen 5 2400G can't do 4K@60hz YCbCr4:2:2 10/12bcp in Win10

Why does the Radeon-driver keep defaulting back to 8bcp when I try to select 10 or 12bcp in 3840x2160@60Hz / YCbCr4:2:2? 12bcp should be supprted under the HDMI 2.0 specification.

 Setup:

  • OLED55B6V (has HDMI Ultra HD Deep Color set to 'on' and the HDMI-input is configured to PC)
  • AMD Ryzen G2400G on a new Asus TUF B450M-Pro Gaming with 2.0b HDMI out
  • Driver 19.5.2
  • Cable is fine (I tried a new cable supporting 8K but same result)

Only in YCbCr4:2:0 am I able to set a color depth of more than 8bpc (10 and 12bpc are available).
