It's a valid and very appropriate _question_, which is what I was trying to pose and not make assumptions. The heart of my question is what happens?

Apparently, dynamic range is decreased.

What happens to color, contrast, noise, saturation, etc?

Afterall, if you go higher in ISO from the base, there's a tendency to get more noise, more "grain-like" appearance, lower dynamic range, muted colors, etc. Does the same occur when decreasing ISO from the base ISO 200?

Thank you
