The words "should detect some anomaly" is already a presumption.
Note that some restrictions have already been placed on "extra
dimension theories" based on an actual submillimetre experiment.
See "Upper limits to submillimetre-range forces from extra
space-time dimensions," Joshua C. Long, et al., _Nature_, V. 421,
pp. 922-925, 27 February 2003.
