To me it seems like its saying 'here the extra's you get with premium' so I'm not convinced by this alone that all aesthetic customisation is going to be paywalled imo I think there'll be the usual hairdressers and clothes shops in f2p, then there'll be a few 'premium' cuts/clothes etc only available at these locations to the paypigs

'go change your haircut/clothes' traditionally being one of the first missions in GTA games, the backlash would be great if there was zero customisation of the base characters available to people who 'only' buy the base game

of course I could be wrong, god knows studios have learned pandering to whales is more profitable than making the base game as good as possible to attract more buyers, I just don't think this by itself is evidence all customisation will be paywalled as many seem to be assuming
