I suppose that the graphical library simply copies the raw values to output pixels without interpreting them (as it should). In true 256 color mode (on old systems, before the effective deprecation of all the color conversion and matching routines) that would probably use the current palette. In the early 90s, if you had a lot of GIFs sharing the same palette, and knew that the program displaying them had already set it once, you could skip implementing all the palette handling.
