Indeed, the gdallocationinfo was returning just one value. After rebuilding the VRTs with the -separate flag, it now returns all values. Great, thanks!
Now I need to fix the GetFeatureInfo, it still returns one value. I guess I need to change my getfeatureinfo template file. I'm not sure how. Any clues?
