SaturationColorShift SD14 all RAWDevs except RT5.0

I notice that one of my critical SD14 X3F which show unnatural color shift which do not exist on the location to my eyes changed significant in RT5.0.

My guess is that in LibRaw which I think is used as base for RT5.0 there is significant different method to recover highlight color.

The scene is very difficult. A mixed of mercury, blue LED and skylight. The whitebalance is on a white sign above the container in RAW development.

The chrominance noise reduction is 40 with Lab space in RT5.0 which come close to SPP4.2. All SPP above 4.2 are equal. Kalpanika 0.54 show the best trade of noise versus detail but missing the dead pixel removal as all other except SPP.

There are color shifts below saturation and at saturation!

All developers show different behaviours seen on the street and the lamps.

SPP4.2 white balance on the sign above the container. All other neutral.

RT5.0 with Chrominance NR=40 Lab

Kalpanika 0.54 NR I assume within KPN -> TIFF(16bit) -> RT5.0

Silkypix 5.0
