3-D Secure browser info from mobile app

The 3-D Secure lookup API requires a browser object. We're processing in a mobile app and not within a browser. We're using the Cardinal Mobile SDK to perform the device data collection, but it does not appear to return data that can be used to populate the browser object. Is the expectation that we should create a browser object with only the deviceChannel field (set to SDK)?

If the deviceChannel is set to SDK does the 3ds/lookup return an error if the mobile device data collection step is not peformed?
