Unlike wax, the acrylic finisher has a significant effect on the way how leather creases.
No question that the acrylic wax is a thicker, more cohesive coating than a natural wax would be. Spit shine the joint area of a shoe and then walk it...even for only a few minutes. I think you will be surprised at the results.
Then too, there are a number of different formulations of acrylic waxes. Some can be applied directly, some require "conditioners" of various strengths to prepare the surface. Some, as I suggested, are high shine, some are satin. Some are more flexible than others. some are even forumlated for shoes...where flexing is expected...and some are formulated for other kinds of leather goods. Or even floors.
Part of what you're seeing there is the effects of light reflecting off the acrylic. The leather is still creased in the unfinished area. It's just not as noticeable.
Keep in mind that many if not most leathers (shell is an exception...usually) that are very shiny have an acrylic finish on them. That's the way they come from the currier and that's the way they are marketed. But you don't necessarily see the effect you've photographed here on those leathers.
