Thank you for all information, I see the problem is in CMOS sensor 4K, I rather choose 6K.

It's not a sensor problem. The GH5s, Terra 4K, Z-Cam E2 and Pocket 4K all use the same sensor: Sony IMX294/299. None of the other cameras has the gamut clipping/red turning pink issue nor problems with wilt looking foliage. It's a BMD Film V4 problem.

Only a color science update can fix it.

Resolve 16.3 beta 3 new Gamut Compression option in RAW tab now fix all problems with color clipping in Gen 4 as well as in Gen 5. It just makes Gen4 behave same as Gen5 and protects extreme saturated colors from clipping when you do color and gamma transformations inside RAW tab. This is only for BRAW yet. DNG don't have this option.

Wish it was coming for cDNG also.

Yes, what I was asking for, apart from the ramping.

The most interesting thing is that Gamut Compression in BRAW works very different than Saturation Mapping in CST node. Gamut Compression handle colors very similar to RED IPP2. So i really would love to see this option in DNG RAW settings as well as in CST node.
Also some slider to adjust Gamut Compression strength may be useful.

We plan to add it as an option to the CST plugin but no plans to update DNG.

Thanks for info! CST plugin with Gamut Compression is more than enough to make DNG look nice.

In case it works exactly the same way, that would be great!

Has this feature been added to CST plugin yet? Or is it the “gamut limiter” plugin? Trying to compress my gamut...

There is gamut mapping in the CST plugin and the gamut limiter plugin which all do similar things so you could use them if they get results you like. The way its done in the Blackmagic RAW SDK is different and we'd like to have it as an option in Resolve's tools also but the Resolve team has not had time to add it yet.
