As PerroneFord says, hot pixels are a way of life with digital imaging. But I am also surprised at the appearance of yours at ISO800.
When I first got my D7000 I had a stuck Sensel almost dead center in the image. But within a few hundered clicks it fortunately somehow corrected itself. Not saying yours will, but they could.
If they do indeed appear in the exact same locations, than sending it to Nikon will allow them to map them out.
