I believe you have the latest version of the OS.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
I know what you are saying about the look of the Verizon Note 4... For some reason mine also has the same green icons and what not in the drop down.. My Samsung tablet updated and has a MUCH nicer looking blue layout. Not sure if Verizon did this to us or what happened but I am also not happy about it....
