A circa-2017 site plan shows renovations done over the past 3 years. These have added a new Saks, West Wing (indicated in gray) and "jewel box" retail building (in the northeast parking area). Being as how the GALLERIA III section no longer exists, one could surmise that the old "GALLERIA I", "II", "III" and "IV" designations might have been made obsolete.
