Does 8bit->10bit upscale barely make any difference? As there's about x4 as much colors? I haven't tested it, but i do know that newer 4k Blurays will be 10bit 4:4:4 or RGB (Rec 2020), along with the dolby vision backlight program.
the UBD doesn't use 4:4:4 at all and RGB isn't supported too.
the bit deep doesn't increase the number of colors. it increases the steps between each color nothing else.
simply changing 8 bit to 10 bit is done using padding.
10 bit output is pretty much worthless with lossy 8 bit source and most TVs dither this to 8 bit anyway.
