Correct application of dither decorrelates the quantizing
error and linearizes the transfer function at the expense of a noise
floor. The resolution becomes, in effect, infinite. The limitation is
that the noise floor can be plainly audible in low resolution systems
and obscure low level detail in addition to being distracting. However,
within it's available dynamic range, the system is infinite. You can't
get better than that, even if you throw more bits at it. Taken as a
whole, the system works better than it would appear from the initial
learning aid of the ideal quantizer on paper. Add more bits, the noise
floor drops, and you can resolve smaller (quieter) details.

If it is so, then it..umm..is so. So this is what happens in the real world,
but in theory
24 bits represents the original signal more accurately than 16 bits.
Thank you Jay for your information!
