6% of a standard deviation sounds like very little to me, but it's hard for me to grok what that actually means.

California GPA average is about 3.0 with 1.5 standard deviation. A 6.4% SD improvement would be a 0.1 point improvement in GPA. Certainly not an overwhelming result, compared to the subjective reactions how phones and screen are “obviously” destroying kids lives/attention spans/ability to hold a conversation, etc.
On an IQ test for example that would be just under 1 point of difference.
