Going from a RGB and exporting as a gif does produce 256 colours and looking at the colormap, magenta might not even be there.

As Blighty wrote, you can edit the colormap to make sure magenta hex ff00ff is there
As an alternative you could try reducing the number of colours before exporting as a gif.
Convert your RGB image Image -> Mode -> Indexed and choose the option Use web-optimised palette

That gets a reduced colormap like this with the main color magenta. Now Export that as a .gif

As a check changing the magenta to a different color shows the extent of the color.
