Thanks for taking the time to answer Orash!
I'm not sure what I'm asking either, but thing is, on Resolve, if the color science of the project is set to ACEScct, using a LUT on the node tree won't clip the highlights at 100 nits when you change the ODT for HDR, in my case, Rec.2020 ST2084(1000 nits, P3D65 Limited).
I also agree it's not a good idea, but I've done 17 episodes that way and could't see any issue on the image, also all the HDR masters passed the QC of the TV channel without any problems.
I'm trying to find any other issue that I'm no taking into consideration right now or if there is anyone doing the same thing out there.
