Perhaps it is just about how you open your GeoPackage. See

"Opening options

By default, the driver will expose a GeoPackage dataset as a four band
(Red,Green, Blue,Alpha) dataset, which gives the maximum compatibility with
the various encodings of tiles that can be stored. It is possible to specify
an explicit number of bands with the BAND_COUNT opening option."
