Two possibles, your line is an E/O line, one that is delivered directly from the exchange , if that’s the case it doesn’t go via a cabinet, making Fibre To The Cabinet impossible , or your line is incorrectly recorded as E/O on Openreach database, but in truth does go via the same cabinet as your ‘neighbours’ lines do.
I get the impression that your neighbours are not necessarily that close to you, usually it would be unlikely that near neighbours would be served differently, but in a rural situation that doesn’t necessarily follow, you may refer to a property are neighbouring but is 30, 40, 50 metres or more away
