This is why I shoot in raw format. By the way you could use expert raw/promode and shoot at 24mp or 50mp. Not sure about 200mp.
This will give you control over the white balance, sharpness and colour grading. Saturation on its own can discolour things. Individual colour channels are better tweaked on their own. Reducing and increasing channels let's you create a more balanced look.
Only downside is you are going to need lightroom and lens profiles to fix any spheric distortion. You can also try the presets and adjust to taste.
If I can use it anybody can.
If you still want to use jpeg/heif processing turn off the scene enhancer. Computational photography doesn't always get it right.
I know people want instant gratification and social media ready photographs.
To be fair, every camera sensor has a look to it. In general, everybody is using iPhone stills as a benchmark . Really you should be making comparisons to a compact camera.
In the case of too much green, it maybe that the red pixels are not being processed properly. Photographing a colour chart would confirm which part of the pallette is being misrepresented.
In technical circles, you are looking for 18% grey (256,256,256 x 0.18 which equals grey in 8-bit rgb). 50% grey would be 124. I'm going to cite this information further.
Sorry for complicating things although I hope my brainfart does explain some peculiar discolouration.
To be fair, Samsung should fix this so you as a casual snapper don't need to worry about this sort of thing.
