Also my earlier comment about colour channels cannot be illuminance still stands. It is a term that "only" applies to light measurements with a particular frequency / sensitivity curve. The colour channels should all be in_intensity_xxx_raw. If you want to do the computation in driver to derive the illuminance that would be great, otherwise we shouldn't have any illuminance channels.
