As well as having become a synonym for posh or poor, there actually is two types of loaf here in Scotland called by those names. Plain bread is a 'batch loaf' and comes out the oven like a big bar of chocolate, it is then split into 'oblongs'. The resulting loaf has a thinnish dark curved top crust, and a flat thicker dark brown crust on the bottom, with no crust on the sides or end. A 'pan loaf' is what it says it is, being baked in a single loaf tin or 'pan' and has a golden crust all over, as it is baked singly it costs more, so can't be afforded by us poor folks. Both loaves are white BTW.
