TDA4VH-Q1: AWB Tuning for AR0341 sensor

Tool/software:

HI Experts,

I am trying to tune the AWB for AR0341 image sensor. In AWB tuning we need to capture raw image at different lighting conditions and give corresponding exposure values as shown in the below figure

But for AR0341 sensor Analog gain is not controllable from host side.

So for AWB tuning is it mandatory that we need to give exposure time, Analog gain  in the corresponding fields?

Or Color temperature is enough along with captured raw data?

Thanks.
