Do not confuse Part 135 Rules for Part 91 Rules.
I do not disagree with the import of your statement....just the way you arrived at it as we both agree about if there is nothing to see outside....you are surely flying purely on Instruments.
all regulations are underpinned by the definition of terms that span all parts.
If you start with your region of choice, lookup the definition of visibility. Then go from there.
Visual flying is bound to the reference of ground objects and a visible horizon (among other minima) and being clear of cloud, unless on/over the top is accommodated.
