The 365s started to get the white livery with 'stickers' in when they were refreshed around 2014 (might've been a year or two earlier). Those of us on here at the time referred to this refresh as a 'dumbing down' of the trains to get us used to the class 700s.
The 700s were ordered when First Capital Connect held the franchise so I'm not surprised they were ordered in an all white livery given there would've been uncertainty about which train company was going to hold the franchise once they entered service.
