Just dug around a little bit more and it seems as if the default colour Excel associates with the 'automatic' value is black. That would explain why you saw that odd appearance but does raise the question of why POI returns this value for both the backgrond and foreground fill colours after recovering the style from a cell.
If I have the time, I will use BiffViwer to look alittle more closely into the data POI is recovering from the files.
