I did a little experiment, adding a Depth 30 setting to the Display
SubSection for the Screen (and removing all lower depth entries) also
a DefaultDepth 30

Judging by the scrambled wallpaper, this did at least change the
memory buffer layout! But the AV amp still reported the colour depth
as 8 bit, not 10bit, any other knobs I should have played with?
