Color correction (aka white balance) has been one of my biggest struggles in photography and I've seen automatic white balance (AWB) improve very little even in high end SLR and mirrorless cameras over the last 8 years. Some interchangeable lens cameras (ILC) like the Sony Alpha 7S III have separate "visible light sensor" which I've heard is used to augment AWB but it's a relative rare feature; if the ILC companies made it common by now I suspect the reason might be that you just can't compete with an incident reading or that it isn't much better than just reading from the main sensor.
