Mean subtraction of OpenCV face detector

I have seen the README.md in https://github.com/opencv/opencv/tree/master/samples/dnn

The mean subtraction of OpenCV face detector should be (104, 177, 123) for BGR, but both test.prototxt and train.prototxt in opencv/samples/dnn/face_detector show the mean_value for channel G is 117.

Did I miss something?
