Kalani has always been Kalani (same focus, intensity, drive... etc).

What Kalani didn't have was resources:
Access to better team S&C ($$$$)
Access to better team Nutrition ($$$$)
Access to better team mental health (the best teams have a large staff of sports therapists)
Access to better equipment (have you seen the new robot QB machine WRs use to train with?)
Access to better facilities (perks = players.. the football facilities are 10x better than 4 years ago)

BYU punched above its weight for years with less than most P5 schools. With REAL P5 money starting to come in, you can see the benefits.
