No. the WHERE condition won't appear in the running queries as you get it by clicking on the upper right button "View Query", if I understand you right.
The 'fetch_values_predicate', as its name suggests, controls how you will get the available values for the filters in the lower left section 'Filters', so you must use it with 'Enable Filter Select' checked, as the snapshot bellow .
When you add a column into a filter, Superset will fetch the available unique values of this column for you to select from. Then 'fetch_values_predicate' put the WHERE condition on the query fetching values, so you won't see it and it is also unnecessary.
