That's an 8 bit pallette size, where each pallette colour can take any 24 bit color value. So yes a program could store only the 8 bits needed to identify which colour from the palette is used for a given pixel, but many programs will expand it out to 24 bits in memory. Plus scratch memory used in any transformation which might be substantial as well. It all depends on the implementation. A smart program could do a scaling operation without storing the original image in uncompressed form at all, and only ever storing part of the resulting image in uncompressed form. It would cost a little in performance, but potentially not very much.
