2016 CTD 2500 REAR DIFFERENTIAL QUESTION

I just replaced my rear diff oil today in my CTD 3500. It's 11.5 rear end I used Amsoil 75w-90. I bought 4 bags or qts. My fill mark is stamped on the cover plate about 3/4 inch down. I bent a tool to that mark and filled it up. It only took exactly 3 qts or bags. So did I under fill according to some here on this post?
