Reimport generic binary

Hi, in my work using generic binary I face a issue which I like to get confirmed.

As test dataset I used a small sample of the Interferometric Ultra-Fine Pair ( from the Interferometry Tutorial with RADARSAT-2
From this i created a 6x6 subset for easier investigation (this dataset is attached)

Now I export this set via Export>SAR Formats>Generic Binary BSQ

When now reimporting the exported file, without any modification, I was not able to get the same data…
The closest configuration (in respect to the range of the given value) was image

Can someone confirm that the export/reimport of the exactly same dataset yield not to the same result?
