Do you recall a scene where you saw this noise? My assumption (as I've said before) is that this "noise" is high frequency detail that is actually in the source. The fact that you don't see it with e-shift enabled wouldn't surprise me, as I have to believe enabling it will remove some of this detail. Unless things have drastically changed, the pixel response time in the LCOS chips is already too slow for normal film content. Turning on e-shift requires these same chips to switch in half the time as before, which must result in some loss of detail. For static images this effect is probably not visible, but when things are in motion there has to be some degree of resolution loss occurring.
Normally this type of noise is attributed to the dithering effect used by DLP to generate color tones. One way to rule this out as the cause is to find the scene where you see the noise, and then hit pause. Go up to the screen and see if there is any visible dithering noise in the paused image. If there isn't, it means the noise you are seeing is high frequency noise native to the source (like mosquito noise or film gran) and isn't an artifact of the Sharp. The fact you don't see it with e-shift could be because e-shift is smearing out the detail (averaging it over several pixels) in a kind of noise reduction.
The other option could be if you have the "Color Enhancement" option enabled. In my testing I found that this significantly increased dithering noise, and it is set to level 3 by default in Move 1 mode. For all my viewing I have this turned down to zero. You might want to try seeing if it is turned on, and if so disable it before watching the problematic scenes again.
I still remember years ago when I saw either the RS-1 or the RS-2 for the first time. I had just recently watched Spider-Man 2 (if I remember right) in the cinema on a DLP unit and recalled how grainy the film used in that move was. But then watching it on the JVC I was shocked that it was almost invisible. The picture didn't look anything like the source, it was much too clean and smooth. It was pretty clear to me at the time that the JVC just couldn't resolve the grain and it was getting smeared out. I assume things have improved on the JVC side since then, but then again adding e-shift into the mix can't help matters out.
