Question about OTA and Purchasing

Can anyone tell me if I buy this phone new from Verizon or Best Buy, will the phone automatically have the most current firmware update or will it come with one of the rootable G920VVRU1AOC3 or G920VVRU1AOE2? I am currently living in another country and cannot be there to check myself and the person who is getting the phone for me does not anything about firmware or how to check it. Any help is greatly appreciated.

Thank you,
Spenser
