How can I use kodak 2383 lut in the ACES workflow

For example, in Resolve, if you are in an ACES color management, you can right click on your clip and apply the Resolve-supplied “LMT Kodak 2383 Print Emulation”.

I have only done very limited testing of this LMT, but when I initially looked it seemed to be extremely limited in dynamic range, clamping the output below diffuse white. I do not know if this has changed in recent Resolve versions.

UPDATE: I just compared the version of the Resolve 2383 LMT I originally pulled apart with the one that comes with the Resolve 17 beta. They are not the same, so you need to do your own testing.

UPDATE 2: Resolve defaults to applying LUTs in timeline space, i.e. ACEScct, but the 2383 LMT indicates in the <InputDescriptor> and <OutputDescriptor> fields that it is ACES2065-1 in and out, as a true LMT should be. When the LUT Processing Mode is set accordingly, it becomes clear how significant the clamping is, with Rec.709 output clipped at about 82%, never mind HDR output.
