Nope, physics, and levers don't work that way. If you put 1 pound on the 3pt, it's taking weight off the front axle. Every pound you add to the 3pt is taking weight off the front axle, because it's gradually transferring it to the rear axle, and eventually, you could have zero on the front axle (if the tires lift).
In a practical sense, my loader can lift almost as much as yours (2,638lbs at pin), and with no rear ballast, I was able to just barely lift 1,300lbs (weighed as such). With that 1,300lbs turned into a 1,350lb counterweight, I can put my forks under something I can't lift at all (FEL hits relief) and the rears stay planted. That is clearly taking a lot weight off the front.
Most importantly, as you said, it should be used as designed, and Kioti specs 1,047lbs on the 3pt for FEL use. I don't think they did that by mistake....it's to protect the front axle, and keep you safe.
