vision.detect('img.jpg', ['properties'], (err, text, resp) => {});

Response based on the https://cloud.google.com/vision/ returns much more details then above call e.g.

        }
      ]
    }

... while the same request for the properties via lib call returns only:

{ "colors":
      [ "996730",
        "4b2c19",
        "180f13",
        "e0c26c",
        "ac702b",
        "7f7976",
        "7f5121",
        "c88641",
        "c48c53",
        "75582c" ] }

Similar to #1881 all available details should be provided in the response.

Looks like adding option verbose returns original details.

vision.detect('img.jpg', {types: ['properties'], verbose: true}, (err, text, resp) => {});
