Oklahoma is a shall notify state, but I saw nothing other than notification that says you have to provide your permit upon initial contact. Although it does say you have to have a state issued ID and your permit on you when carrying concealed.
Now how would an officer know you had them both unless he asked to see them to make sure you were not violating that provision of the law.
As far as imprinting goes, the law says it should be concealed to a normal person. If LEO is trained to notice a concealed weapon, that doesn't exactly count since they have extra training that precludes them from being considered a normal person in that regard.
