Local copyright laws can definitely affect your Netflix library. For example, if you live in a country where copyright protection is relatively weak, you may find that you have access to fewer movies and TV shows than someone living in a country with stricter copyright laws.
This is because Netflix has to obtain the rights to stream each title in every country it operates in, and some countries are simply more difficult (and expensive) to obtain the rights for than others.
So if you're ever wondering why your Netflix library looks different from someone else's, local copyright laws are likely one of the reasons.
