Filippo, What is the format of that raster file ? Can you share a link to the dataset ? or the output of gdalinfo at the very least
I'd note that -128 can only be considered a valid value for a 8bit raster if the metadata item PIXELTYPE at band level is set to SIGNEDBYTE (IMAGE_STRUCTURE metadata domain).
