I may be thinking of something else based on your description. If you got an output that has the original values in the area of the kmz and an alpha mask band over the other areas I think that would be expected. You can also use -crop_to_cutline to remove that 'extra' data. If that isn't what you are talking about, you may want to use ogr2ogr to convert your kmz to a shapefile in the same projection as your input raster and see if it gives you a better result.
