So (as many have noted) parenthesization does not call GetValue in ECMA-262:
11.1.6 The Grouping Operator
The production PrimaryExpression : ( Expression ) is evaluated as follows:

Reference.
NOTE This algorithm does not apply GetValue to the result of evaluating
Expression. The principal motivation for this is so that operators such
as delete and typeof may be applied to parenthesised expressions
