More info on x300 ultra multispectral sensor?

Is there more information about the 5mp multispectral sensor on the x300 ultra available? So far I can only see short snippets saying it's supposedly got 12 bands and is used to enhance the colour of the higher resolution sensors. Can I find what those bands actually are? Their wavelengths and bandwidths, and whether the raw bands will be accessible by third party software? This is probably the most interesting smartphone feature to me since Apple introduced the infrared faceid hardware, except you can't access the raw data from that
