Hybrid is no NLE like DaVinci Resolve or a tools specifically meant for color grading.
It does have some filters in Filtering->Vapoursynth->Color, but that's it.

I assume when you write of 'photoline' you are referring to https://www.pl32.com/ which I have never used so no clue what you are trying to do.
Unlike Avisynth, Vapoursynth atm. has no filters like :

• AutoLevels: http://avisynth.nl/index.php?title=Autolevels
  
• AutoAdjust: http://avisynth.nl/index.php?title=AutoAdjust
  
• SmoothAdjust: http://avisynth.nl/index.php/SmoothAdjust
  

or similar filters and from the looks of it there isn't much development done in that sort of direction.
I'm guessing GradCurve (https://github.com/xekon/GradCurve) might be along the lines of what you are looking for but I have never used it and I have no how it works. From the looks of it it needs to be fed with a curve-file, but it doesn't come with a tool to create the curves,...
