While I haven’t found an “official” statement, I believe the reason is something along these lines:

can differentiate, so that different image enhancement or
modification processes can work better. Like with audio; 44kHz is
about the limit of human differentiation, but 96 / 128kHz is better
for working with it, say for remixing.

If you want to do more searching, you should probably look at the discussions about “imagefile”, which was the predecessor of farbfeld. A lot of the discussions happened back then.

Also, there are a couple of talks by Laslo Hunhold on farbfeld and color spaces, maybe he explains it in one of them.
