I am very doubtful. The question is what values must KSA shed to be "modern" and what values it must keep in order to be authentic. Sometimes these values clash and KSA has to decide on which direction it wants to go. Also, I doubt that 6 years are enough time to change deeply entrenched values at the societal level. The transition of Japan took longer than that.
From an adult development perspective, the shift from pre-modern (pre-conventional) to modern(conventional) is a momentous one and even the West has not successfully navigated this transition as still individuals with pre-modern consciousness account for 40-60% of the Western population. Right now, I see only 10% of KSA population at a conventional level.
