CK BB Steel upgrade from Dura ace BB - is that even an upgrade?

Im changing to 165mm Dura Ace crank (from 172.5) - been having hip issue and tried messing around w saddle position/ tilt - I am stretching my hip flexor everyday and trying to improve flexibility.

When I am changing the crank, I am going to take off the chainring and clean around and need to regrease the crank shaft. well I like Chris King hubs and figured that I would like to try their Steel bearing BB. I like the durability aspect of it and not really sold on ceramic bearing on BB.

Bike is new.. only 2500 miles on it since Dec 2024. Would you guys just wait it out and dont waste money?
