Are you familiar with Nancy Cartwright's work, in particular "How the Laws of Physics Lie"? She argues that universality is traded off against truthfulness. Specific phenomenological laws can be shown to be strictly true, whereas the artificial assumptions and approximations needed to make the data fit with theoretical laws argues against the truthfulness of the latter.
