I just used it over linear gray gradient. Input was set to acescct. Waveform analyzer showed up a change in whitepoint with dci d65 output preset.
The same way I was judging gamma difference. DCI preset make curve “brighter” than 1886 preset. But DCDM (and even probably dci d65/d60) showed up the same curve (despite the different white point of course) as 1886 preset.
Great! Will check it out soon!
Oh, I was sure (and still hope) openDRT will be ACES 2.0 DRT but with slightly tweaked parameters.
What I really don’t like in current ACES DRT is how it clips saturated colors in the shadows. Still have no idea how to fix it in grading. And it’s noticable even by eye on oled screens or on inverse sRGB EOTF displays with rec709 ODT. (And just for statistics: I’m from power law 2.2 gamma club, all sRGB EOTF screens are evil 
)
