I took so much time deer boning and brushing out creases on a few pairs, as soon as you take your first steps they are going to crease exactly how they were before. I gave up and just embrace the creases as they come now, just buffing and brushing quickly before and after wear (along with a damp cloth wipe down). Some pairs of mine show almost no creasing at all, some have beautiful roll creases and some have ugly creases. It's the luck of the draw based on the individual leather, last, and fit.
"Patina trumps pristine" as I read in someones signature haha.
