To all RAW image processing devs: When implementing custom White Balance pickers do allow much larger sampling windows, hundreds or even thousands of pixels. All images have noise that messes it up and you have to average over much larger areas. 32 pixels is nothing @RawTherapee

No. That's a RAW image (from Sony A9 III). On the right is the cranked up saturation to visualize the noise splotches. And it makes it obvious that any averaging window must be much larger than the characteristic spatial size of a noise blob.
