No. The only harmonics to be seen are in the first picture,
the one with *no* dithering.
For final delivery (e.g. a CD) the noise-shaped one should
be the best, it will produce the least audible noise. This
doesn't matter is you have a constant high level, it does
for music with a wide dynamic range.
If the signal is an intermediate one in a production process
(but then why would you use 16-bit), the rectangular one is
recommended.

Thanks, I'm looking at the different dithering types here:

And wondering, which is the "best" of them to use?
Looks to me like the rectangular creates the fewest harmonics. Am I reading this
correctly? I have Ecasound, sndfile-convert and sox. But
from these three I
deem sndfile-convert to be the best. but I seem to remember, that
Fons Adriaensen recently released a tool/library to do the same
task. I believe it is as good as or better than sndfile-convert. I
seem to recall, that there were issues with finetuning dithering,
that sndfile didn't offer. As I said, I'm not 100% syure about that.
That is the 'resample' application, part of the source distribution
of zita-resampler. For 16-bit output it offers rectangular,
triangular or Lipschitz noise shaped dithering.
