I give up on my LUT problem, I'll just switch LUT's when I switch
displays.....a little trade off for a fantastic picture quality I'd say ;)
well you know the s2 is not very sensitive in dark areas, even in "qh"

here's what it gave with the window borders in a pitch black room :

the window borders :
