I believe that the issue Francesco Sauta was having on-set is the same that have been posted here: Colour artefacts or breakup using ACES
The temporary solution is the same one offered by Scott Ryder using CTL, DCTL or the LUT he created to address the issue.
We can find the download links to the files somewhere in the same thread linked above.
The article didn’t say if the solution was applied through LiveGrade on-set or Davinci Resolve.
Since LiveGrade doesn’t support CTL file format, the LUT created by Scott can be used instead.
