You could use the color inspector 3D plugin to investigate this.

The map of one image I loaded has 17187 colours, and the colour scale has 458.
Most likely there is some smoothing going on at the edges of continents,
unmapped regions and the superimposed grid which end up blending with the data
and generating non-LUT colours which need to be dealt with.

I think it will be difficult to know what is going on in the images with any
certainty and it would be better use the original data, if available.
