Bénédict's eyebrows change from scene to scene. With the countess, they are very thick---opaque and seemingly cut out of felt---somewhat shaped into rectangles. Later at the café, they reach much higher up his forehead, and look more like applied fuzz. He then has a unibrow, which wasn't there in the previous scene, and they are also quite bushy and unruly.
The countess is supposed to be very ill, depressed and dejected, and yet she is wearing very obvious makeup, beyond that which makes an actress camera-ready: in addition to very bright coral lipstick, she is wearing very obvious lavender eye-shadow, painstakingly applied, along with matching liner. and her eyebrows have also been obviously defined with dark pencil. All this would indicate that this is character makeup and not subtle "movie makeup". The difference is the latter offers room for suspension of disbelief, but such obvious character makeup does not allow for that.
