I just calibrated my 55 and the 57 as well to look at some A/B of Oblivion, there's plenty of mixed contrast and low APL scenes (any of the scenes with the 'scabs' dressed in black).
The auto iris will only clamp so much in these scenes, the smallest i've seen it go was only with a full black field and it does get quite small. smaller than the lowest possible manual setting.
However, during the fade to black scenes, there isn't quite enough time for this transition, it starts closing and then it's time to open up again for the next scene. this will depend on the length of time of the scene out course. Overall it's relatively invisible but it's also not closing as much as it could with certain low APL scenes so it's hard to put a figure on how much different it actually looks vs. my static iris on the 55.
I am seeing black crush with default iris setting of 1. If someone isn't paying attention, I think it could be mistaken for really inky looking blacks. imo, setting 2 looks much better. The iris closes the same, but you can see the dynamic gamma is not as aggressive in this mode. You can 'mess' with it a little bit here. Watch a scene of the scabs, you will see the shadow detail disappear. Hit the 'menu' button and the gamma quickly changes and the iris opens a bit. Then turn the menu off, watch the iris clamp, it looks good for a second, then you lose the detail at the gamma adjustment kicks in.
When you set it to 2, it looks pretty good and the details are still visible.
I can tell you I still have a liking for my RS55, this is a really nice copy and has held it's own so far vs. the 2 newer generations imo. At least in 2D, 3D is another story best saved for the Sharp 30k..
