This isn't important in my opinion, but it is nice to know what it look like.
*all of these picture from below are gain match and play the same note.
This is what it look like when using clearness param. Over do to see the different.
This is not so good to the voice, as they have less harmonic, and noise are dominate.
In my opinion a healthy voice are the voice that have rich harmonic and most of the frequency are balance in volume, a pitchy voice they lack some fundamental, the higher harmonic are more pronounce but at the end, you are the one who decided which voice is best for you.
It looks like it's in heaven
