I dont know why this keeps being brought up. Since then, Akpom has scored 14 total goals (22 if you count all comps). Gyokeres has scored 51 in that same time frame (and 77 if you count all comps).
It was a statistical anomaly for Akpom (and those two were #1 and #2 in scoring for that Championship season). Gyokeres has gone on to bag tons for Sporting, and is 3 years younger.
