Max RPM is the same for all 3 engines, and the only wear difference should
be on the connecting rods. Apparently the difference isn't enough to change
the TBO, which is a theoretical figure anyway.

Connecting rods don't wear. Their bearings wear, but the con-rods don't
wear. I doubt the slight difference in force on the connecting rod and
crank bearings is enough to cause a measurable difference in wear.
