Though the Scanner app is great, it was built to be a sample of what you could do with the Structure Sensor and Structure Sensor SDK.
If texture quality is what you are looking for, I would look into trying out different applications for the Structure Sensor.
You can find all the applications available by plugging your Structure Sensor into your iOS device, and then going to Settings > General > About > Structure Sensor. Once there, you'll see a button that will take you to the App Store to show you every app available.
You should also look into Occipital's Skanect Software made for both the PC and Mac. It has an uplink mode that will allow you to stream the Structure Sensor data over WIFI to your computer for processing. We just released a new version (1.9) that has a high-resolution color setting.
Hope this information helps! Let us know how it turns out!
