Yes. Apples from the Shinigami Realm look like shriveled green peppers and do not look like normal apples at all. Misa gave a juicy human 林檎, アップル to Ryuk and in return he lets Misa have a bite of an 林檎, アップル from the Shingami realm. Misa took a bite of the 林檎, アップル and spit it out in disgust saying that it “tastes like sand”, so I would say that they 愛 apples from the human realm. :)
