Hi 
I'm on a two camera production with an Alexa Mini and an Arri Amira. Just been aware of a bigger white balance difference in the two cameras intern ND filters. With intern ND 2.1 in both cameras there is almost a 0700k difference, using exact same light and lens on the test. 

Has anyone experienced this aswell? 
And who to contact at Arri? 

Thanks
