The current ACES RRT renders into a virtual display HDR wide colour gamut space (extremely similar to a 10000Cd/m^2, Rec 2020 display). The ODT targets this intermediate data into a specific real display, say P3, Rec709/1886 etc. The general assumption is that it targets a dark viewing environment, and that adaptations are currently placed into the ODTs to deal with some of the image rendering adjustments needed to compensate for dim viewing etc. The work going on to revisit the RRT/ODT is trying to resolve some of the issues that arise out of this particular split of responsibilities, as well as trying to widen the applicability to other viewing situations (personally I'd like to remove some of the colour adjustments as they limit the available colour range and looks that you can create). ACES is definitely not limited to cinema viewing, Framestore use it across almost all of our different delivery mediums, and yes we have hit some of its limits so I'm not a total fanboy - but have provided constructive feedback!
