16 bit GeoTiff imported as 8-bit

I have a geotiff file of Worldview-3, 8-band, satellite imagery. When I view the file in R it indicates the data are 16-bit. A quick view from GDALinfo indicates that it is: "16-bit, unsigned". Similarly, there are a lot more than 255 levels in the raw data. The values for each band range from 1-2047.

 

However, when I bring this file into ArcMap and view its properties it shows pixel depth of "8-bit, unsigned integer" and the levels are 0-255 for each band. Is there a way to import this with all of the data? I am just dragging this file from ArcCatalog into Arcmap, is there a better way to import this file with the raw data? The RGB plots look fine, but I don't want to throw away data for classifications later. Thanks,
