Did the latest FW update change the color reproduction for Wide DR?

WDR looks weird under tungsten lighting, very greyish, greenish. Works well outdoors.

I had a bad experience with WDR indoors and maybe it was because of tungsten lighting. I am thinking about updating my firmware if there is an actual improvement in WDR color. I won't be able to use my other custom profiles so I want to be sure. Also, do you really need a 64GB card to do it? I have a 32GB card.

I think WDR works fine as long as you also use the WDR color Matrix. I cooked up a setting using the EOS Color Matrix with WDR gamma, worked great in daylight but looked awful under tungsten lights.

What do you use with tungsten lighting?
