Only if dithering -- if you truncated then the low bits would be simply removed. If dithering to 24 bits they may give you a bit's worth of noise (which is well below the actual noise floor of any real world converter), and if you dither to some lower bit depth (such as 16 bit) it would likely have a statistically insignificant effect.
