Which detail do I look for
 
Did some field testing with an F3 last week recording to both SxS and NF. In mid-sunny weather I steadicammed through woody environment. I used an AC profile with CinGam 1. Did different approaches on DOF.
At 25p 280Mb/I-frame I just can't find differences in detail when comparing it to the SxS, even with some colorgrading.
What am I looking for? How can I force this difference?

So, no one?
Maybe some real life exemples to post...

If you isolate the red channel, you will see the Nanoflash has superior red chroma resolution than SxS, 4:2:2 vs 4:2:0.

It may also be worthwhile to check you are not recording 1080i as opposed to 1080PsF. That also makes a difference thanks to interlaced chroma vs progressive chroma.

What were the lens and shutter speed parameters for your shoot in the woods?

I've been surprised that not every shoot improves from recording at higher bitrates (50/100 Mbps LongGOP or 280 Mbps I-Frame) when compared to SxS on a Sony EX1 with 10-20 random frame grabs of the same slice in time. Also, I have been surprised that scenes at higher bitrates contain much more noise but not more appreciable detail.

Most of the shoots that have not yielded improvements were captured with the lens at wider apertures (shallowed DOF + lower lens sharpness) and slower shutter speeds 1/30, even on a tripod. Outdoor scenes with shutter speeds of 1/100 and f/4 .. f/5.6 exceed SxS and show an appreciable improvement. Lens and motion blur limit the utility.

Dear Friends,

Here is an image with lots of detail and movement for comparison purposes:
