$( ) is substitution, not quoting.  It is true that if you have both
outer double quotes and a $( ) inside them, then the rules for parsing
command substitution take over until the matching close-paren is found;
but otherwise nothing is quoted differently just because it is inside
a command substitution.

The other major one is aritmetic evaluation in (( )) where everything
behaves as if double quoted, and then there are the special cases in
parameter subscript expressions, which can get a bit strange but in
practice you'll almost never run into.
