Such a very minor difference is not material change and will not affect your use of your visa when you arrive in the US. The details that are being compared are about you, and both the new and old biometric data will correspond. Don't worry; you've taken care to make sure that everything is in order and now all you have to do is to come to the US, enjoy your time, and be successful in your studies. With the diligence you've shown here, surely that will happen.
