Thank you for your answer but I’m a bit more confuse now 
What’s the meaning of scene-referred? I tried using Rec.2100 HLG and Rec.2100 HLG (Scene) as input in Davinci Resolve and the Rec.2100 HLG gives me the same result I had with Output - Rec.2020 HLG in a ACES 1.1 workflow. This is logical, but Rec.2100 HLG (Scene) gives a very bright image even with good exposure, which is visually absolutely not correct.
And even more confusing when you said that the S-Log was correct because I shoot same shot with same settings except the picture profile: HLG/S-Log2/S-Log3. Both S-Log in ACES using the corresponding input transform give me roughly the result I that Rec.2100 HLG in Davinci or Output - Rec.2020 HLG produce with the HLG footage. The only one which looks a lot different is when using Rec.2100 HLG (Scene) as input transform on the HLG footage from the camera. Is it really how it should look? and then, why? No matter what timeline color working space I use in Davinci, Rec.2100 HLG (Scene) is always too bright, so, I don’t believe this is correct and what I get initially with the only HLG option available in ACES 1.1, looks the more accurate.
