What is the impact of not having the blue band for DJI Mavic 3 Multispectral?

The monitoring of most crops and vegetation relies mainly on near-infrared, red edge, red and green bands. For example, the NDVI, NDRE and GNDVI indices, commonly used for crop health monitoring, only use two to three of these four bands. Therefore, the absence of the blue band will have minimal impact on applications such as monitoring of crop growth and environments, as well as natural resource investigations.
