No, it doesn't require that level of noise exactly, it requires that

the quantization.
It sounds like you're just trading one noise for another. Since it is
noise
either way, what's the advantage, particularly if it is inaudible?
Quantization noise related to real world audio signals is both coherent and
represents aharmonic distortion. IOW, nasty sounding and audible if anything
that level is audible. Not easily masked.
Normal random noise of the same level is always preferable. The noise
related to dither can be spectrally shaped so that it is far less noticeable
than red, pink or white noise of the same amplitude.
