It's actually very simple.The error in the reconstructed waveform due to quantization errors results in a amplitude domain error and a time domain error.
Imagine the reconstructed signal crossing zero in between samples.
Suppose the least significant bits of both samples are rounded down then it's easy to see that the signal crosses the zero a bit too early.The higher the bitaccuracy the better the point will be defined where the signal crosses zero.
I don't think the maximum slew rate improves since the maximim change is bound by the output filter and the maximum Vpp output from the output.
However higher bit precision means that the ***minimum*** rate the signal can change is much lower.
