According to Red engineers there are variations in Helium sensor. Some are more greenish than others.
Mine is definitey on the greener side. Sometimes -20 Tint to compensate. Not sure your Lut would be much help though.
The LUT does expect white balanced footage, so some of the tint would need to be manually corrected. With that said, the Alexa LUT does pull some green out of the image - especially skin tones.
