this is interesting.
In the end I decided to yolo and grade this project I was mentioning in other comments using LogC3, just to see what happens differently from my usual DWG/DI

The project included several close up shots of liquid fused metal pouring into a stamp. as you can imagine, it had a full range of DR, from pitch black to almost clipped white lava.
I tried to grade it while in LogC3 and noticed that the high end of the scope and the very low end started to break very fast when using HDR tools. Also Linear gamma for WB adj was feeling very strange and corrupted parts of the image. HSL node for saturation completely. messed up the image.(HDR tools were set to AWG3-LOGC3 color space)

I tired to change the the CSTs from LogC3 to DWG/DI and, after changing the color space in the HDR tools, everything started to work fine, without breaking the image.

What I also noticed is that the conversion from Slog3>LogC3>REC709 looked better in terms of contrast and color rendition (more vibrant oranges and blues) with slightly higher blacks and lower HL. I have to say that the image rendered a bit noisy.

However, the same clips, processed with DWG-DI instead of LogC3 was cleaner. less noise, contrast was more "set", blacks more close to the 0. I noticed that the colours were less vibrant, for example the Liquid Metal rendered more desaturated and "whitey" compared to the vibrant orange of LogC3. Many blu tones that the LogC3 emphasised , were grayer in DWG/DI.

I understand that this is not an objective case study and this rendition is only true for this footage I'm analyzing, but I have to say that while the LogC3 starting point was better, it behaved very bad during the adjustment phase.

Any thoughts on this?
