A wastegate doesn't bleed boost to atmosphere, it bleeds exhaust gas around the turbine. No boost is lost since it is not 'created' because of the bypass.
A blow-off valve might bleed boost to atmosphere but more typically back into the turbo so as not to confuse the airflow sensor. This is only useful for engines with an air throttle plate... and ricers who like that
