Every idealscope image is specific to the diamond.. you question is a bit like asking if a photograph will be the same for two different people. If the people look similar, the photos will look similar.
It two diamonds are cut very well, then the idealscope image will have similar characteristics, but the similarities and differences depend on each and every facet and angle.
There are guidelines for what a "good" idealscope image looks like, and these criteria can be easily found by searching idealscope image. However, it's probably best to just post whatever image you receive or make so that it can be evaluated by a more trained eye.
