Hi, Perhaps this can help: https://gdal.orgdrivers/raster/gpkg.html
“Various kind of input datasets can be converted to GeoPackage raster : Single band grey level Single band with R,G,B or R,G,B,A color table Two bands: first band with grey level, second band with alpha channel Three bands: Red, Green, Blue Four band: Red, Green, Blue, Alpha GeoPackage rasters only support Byte data type.” My guess is that if the original raster does not correspond to one of the categories above, it will be converted to the closest format.
