may i ask why the ld audio was upconverted from 16bit to 24bit?
afaik re-sampling ld audio from 44.1khz to 48khz for dvd/bd usage is basically lossless, if a high quality sampling tool is used. so is there any benefit also changing it from 16bit to 24bit?
Nope. If it's 16 bit to begin with, you can't create more detail. (And even if you could, the difference between 16bit and 24bit is impossible to hear, unless you have magic ears.)
