at which switch was turned between picture 3 and 4? Are those dimmable ceiling spots with LED and different color temperatures or is there also a light in the window lintel?
These are quite certainly tunable white lights, which may be controlled and set via KNX. We have that too.

These are RGBW spots, yes the color temperature was adjusted, he mixes blue light into the warm white light.
