Same here. Got G.Fast almost 1 month ago via Sky. The OR checker now shows the same speeds for G.Fast as for FTTC but it was previously accuratel Our line is 175 metres from the cabinet.
There is FTTP in adjacent streets (Openreach & CIiyFibre) - but our little private estate has been missed. No idea if we will ever get FTTP, so G.Fast is as good as it gets here.
