Therefore I believe its in the encoding that is the issue, basically..
how can I improve this? People must have come across this issue before.

I am not sure of this, but I suspect GIFs make come in two flavours,
ones with a palette map and ones without. I would suspect an animated
gif must have a common palette map for all frames. If they don't, you
get some sort of inefficient kludging. So it seems logical you need to
massage the frames to give them a common palette map before feeding
them to the animation gluer.

It would be extra overhead to have a different palette map for each
frame. Given the age of GIFs, that overhead probably was totally
unacceptable originally when the formats were nailed down.
