I suffered a power outage at home, facing the following problem hours after when trying to turn my PS4 Pro on (sorry, my PS4 language is set to Spanish, but I'm adding a translation with every screenshot):
Translation: Checking the system's storage status...Don't turn your PS4 off. When the check is over, your PS4 will reset automatically: 
Then the following message appeared:
Translation: A serious error has occurred in the system software. The PS4 will restart 
This process was triggered when I selected the fourth option here (Restore Default Settings): 
Everything is back (surprisingly, even in-game screenshots!)... but the game saved data, which is gone:
Is there any way to get it back?

Unless you backup your saved games locally or use PS+ cloud storage (with or without auto-upload), it's gone. If you do backup your saves, you can transfer them back.
