Does changing the ISO alter the visible noise?

With digital, the best practice is to expose for the highlights and recover the shadows.
If there is enough light, use the lowest practical ISO to get the most DR.

We [should] already know that visible noise (signal to noise ratio aka S/N or SNR) is the determined by exposure, not ISO.
When I view images on my monitor, especially images of people wearing black clothing, the noise is very visible in the clothing. Therefore I conclude from your explanation, I should expose for the dark clothing and then post process to darken the overexposed skin tones?
