Call for white balance finetuning samples

Hi all.
I’m looking forward to create samples for camera support, white balance and noise reduction for Panasonic Lumix DC-TZ99.

I would like to know if:

are white balance samples still useful? This post made me raise some doubts.

for which camera white balance modes should I take samples? TZ99 has the following modes:

  • AWB
  • AWBc
  • AWBw
  • daylight
  • cloudy
  • shadow
  • tungsten
  • flash
  • custom (with manual white point measure)
  • temperature (I can set any color temperature from 2500K to 10000K, by 100K intervals).

I figured out that I should not take samples of AWB and custom, and take samples of daylight, cloudy, shadow, tungsten and flash, but what about AWBc, AWBw? Should I take samples of specific temperatures? And in that case, what temperatures?

Thank you in advance
