Yeah I agree. Lando is country super posh. Oli is more so but Lando doesn't have quite that "rah" posh boy that he might have if he'd been in school longer.George and Lando? Most definitely not. Landos family are silly rich, he went to private school with the beckhams and George’s family are well off and really well spoken, he also attended grammar school. See tbh I’m from Essex (not to far from where Alec actually grew up ) but what I will say is for the Uk, they both are posh
George has a Lincolnshire kind of accent. Not massively posh but annunciation makes him seem posher. You get a right twang of his accent sometimes.
