Are you assuming that the derivative at the origin is equal to one? If you are concerned about the consequences of said adjustment, work differently: I do not understand your comment about the Koebe function in the edit. It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis.

I thought I was using standard terminology, at least it’s the one used in Conway’s Complex Analysis Volume 2. In that book, Koebe function and all of its “rotations” are functions of the form I wrote in kebe edit. The removed set is shown below in blue: Email Required, but never shown.
