Raster image orientation

I would assume that the amongst the 30 to 40 file formats handled by
GDAL that some store the image data with pixel zero in the bottom-left
corner and some store pixel zero at the top-left corner. Do RasterIO()
and associated functions which give access to raster image pixels
rationalize these differences and always provide top-left pixel zero
image to the client? Or do client applications need to flip images
vertically for some formats?
Sorry if this is an excessively stupid question...
