Every raw converter processes color somewhat differently. There is not an absolute standard. I am a PhotoLab 4 Elite user and beta tester and I'm very happy with their color rendering. However, I've also read on a number of occasions that Capture One Pro 21 and Lightroom's colors are more accurate than Photolab's. Whether one prefers the colors of one PP program over another may in part depend on the specific image and the expectations of the person doing the looking.
It is also not clear whether or not there is an even playing field here. Most raw converters/processors automatically apply corrections when opening an image. Lightroom does, Photolab does, and I suspect that Capture One does it as well. With regard to Photolab, which preset is being specified in preferences for new raw images? If you haven't changed it, it is most likely DXO Standard. If you change that preference to use the No correction preset, things might look very different.
The only valid comparison of color rendering between the software programs is to view them without any adjustments applied. Since Capture One, Lightroom, and PhotoLab are often considered the three best raw converters available, in the end they are all capable of excellent results.
The real problem is that there is NO RAW conversion program that doesn't apply adjustments to the image. This is what you would get if you were to render out a RAW image, just applying the colour tone for each element of the Bayer CFA.

So as this is not very useful at all we need to use some sort of default processing. The default processing of almost all converters has changed somewhat over the years, even my choice Lightroom since I started with V3 back in 2011. Still this is the result of using the Lr factory defaults, with the exception of using Adobe's Auto WB, since I shoot UniWhiBal in camera, and we don't need another green image.

Finally this is the final image after I edited it in Lr. It hasn't been through Ps or any other pixel editing program.
Some of the things that I have done to this is change the profile from the new Adobe Colour to Landscape, set a custom WB that is significantly different from the AWB, 5250/+35 compared to the AWB of 7500/+30. I have also added +25 Vibrance and also +75 saturation on the Reds in the HSL tools. There are also exposure and and other levels adjustments applied in the basic panel too.
Now for most modern converters it's very easy to change the default settings to those that match your preferred way of working. So, maybe we should really be asking how easy is it to set your own default conversion? Also can you have the software set camera, and even ISO specific default conversions? Because that is really what you want to be doing IMO.
