Yes, some kryptonite leaked through and he could see it as he lifted. It's not so much a plot hole, as much as a demonstration of his force of will, using every bit of the energy he absorbed (and remember, he still had a tiny fragment of kryptonite stuck in his side) to lift it into space. We saw the effort nearly killed him.
if you use that logic then the kryptonite shouldn't have effected him in the first place since supes had been "flying high" all day absorbing energy. the whole sun dip thing is dumb enough, Singer just complicated the matter.
