No, it will not, which explains the intrinsic value of the "original" of most anything. An attempt to copy an original in every detail has a variable degree of social acceptance. To some 'faithful' reproduction is highly desirable while 'counterfeit' has lower acceptability.
The operative term here is copied "exactly."
No copy is the same as the "original."
That is the essence of the ability to diagnose or evaluate the fidelity of the copy (and related processes) to the original.
Quantitatively comparing the two is not so simple. The answer lies in the preparation of the original. Make an original that makes what you want to copy difficult. If you want to measure acutance, use fine lines. If you want to measure density, use greyscale, etc. If you want to make an original that is difficult to reproduce you must use unconventional materials, processes, and configurations. Investigate steganography or the embedding of information into seemingly random patterns.
Your question might be beyond the scope of of the graphic design stackexchange site.
Qualitatively, the practical answer is that if you cannot detect a difference, the two can be considered the same.
