When any four-band raster is uploaded to geoserver, the 4th band is automatically assigned as alpha channel. Furthermore, the band names are renamed to RED, GRENN, BLUE and ALPHA and the Layer Preview (WMS) section gives a blank image.

On the other hand, when a five (or more) band raster is uploaded, no band is assigned as alpha channel and the bands names are not renamed. In this case, the Layer Preview (WMS) section gives an image with the 3 first bands and rgb.
