This is an interesting question. The partial metering system should give the same result for both of these scenes, but if the matrix or evaluative system is working you should get very different results. With the black door, the matrix/evaluative system should think: "the outer segments are brighter than the center this is probably a backlit scene - give the film more exposure than the average metering calls for to avoid a dark face." With the white door, it should think: "this might be a bride against a black/distant background, give less exposure than called for to hold detail in the dress." At least that's what I hope it's doing!
