Seems the same issue as #1445

That was my first impression intially too, so I started another job to process only the Multispectral TIFF files without the JPG's and I got the same blue results:

Yes, that's because ODM will currently drop the JPG images and only keep G, R, NIR and Re.

I'm working on a potential fix, I will share in the upcoming days..
