Just an update: I have circumvented this problem by editing the palette directly, without adding channels or anything overly complicated. Here's what I did in case other people experience similar issues: I modified the color with index 16 from #878787 to #898989 (editing html notation). This changed that color everywhere in the picture. Then I edited the index 255 color's html notation as well, from 875487 to 878787, which again changed the color everywhere to the correct value. After saving the file, I can now freely edit and export it in GIMP with no further issues, the game properly recognizes all the colors.
