[DCP-o-matic] Rec709 vs BT1886 for DCP

Hi Carl, I have color graded a project in Resolve 12.5, color management is set to Rec.709 gamma 2.4, monitored the same on a Flanders. Taking it in to DCP-O-matic and I see the Rec.709 preset is locked at 2.2. If I change the gamma it changes the preset to BT1886. Is it safe to say this would be correct? I have seen debate as to whether BT1886 is the same as Rec709, but with a 2.4 gamma spec. I'm not an expert on this. Thanks in advance and thank you for the work you do on this software.
