Perhaps has to do with measuring accuracy of center-weighted or evaluative exposure meters, since that kind of contrast sometimes confuses them. It was one of the faults of early (firmware 1.0) Olympus E-300s. A number of reviewers complained that the exposure was thrown off by a light object near the center of the subject.
