ACES has been used with the Dolby Vision projector and does support it.
However, in v1.0.3, there is currently no officially released ODT for P3D65 ST2084 108nits, which is why Blackmagic has not built it in to Resolve. This transform requires an ODT tonescale that differs from the existing 48-nit, 1000-nit, 2000-nit and 4000-nit tonescales provided in ACES v1. The 108-nit tonescale that has been used for Dolby Vision is “experimental-level official” only. Implemenation-wise, workflows that have used ACES w/ the experimental Dolby Vision ODT have baked the CTL into a LUT for insertion into Resolve.
