It all depends on the mapping and the adaptability of the ECU, modern ECUs are amazing pieces of kit and can adapt fantastically well.
Pretty sure i remember reading that most quoted petrol HP figures from new require super unleaded, and the car will produce less if normal unleaded is used. Even though the sticker inside the filler flap or the handbook wont specify Super, as the ECU can manage perfectly well on 95.
