The bump mapping scale of LuxCore scene is something like 10x larger, are you sure it is the same scene ?
And Cycles is clearly lacking of the Shadow Terminator fix:

same scene, opened and rendered with cycles, same texture, same mapping and I tried to match bump strenght as best I could. With luxcore those dark areas appear even with very low bump values.
Yes, it's still not in master. But on the second page of this thread I posted pics from developers where they have it implemented and it's not turning bump mapping black.
Your LuxCore material has 10x UV scale applied:

LuxCore scales the strength of the bump by 10 if you scale the UV by 10. This is a side effect of how the code is written (and probably was written in old Lux, I don't really remember). The logic was to scale all bumps (not only UV width/height but also how much they are deep or rise).
