Well, I mean, if you want to get down to it, on a small enough scale, NOTHING is "flat". There are three kinds of CRT screens: spherical (curved horizontally and vertically), cylindrical (curved horizontally but not vertically, pretty rare these days I think), and flat (curved neither horizontally nor vertically, at least not in any meaningful amount). Pretty much every "flat CRT" these days is about as flat as glass can reasonably be expected to be.
