For bigger differences between the y_true and y_pred you could consider to use the mse loss instead of mae loss; in case of the RMSE/MSE, as the errors are squared prior to being averaged, the RMSE gives a higher weight for larger errors. The problem is that you divide to y_test, hence the difference in results.
