The Arri's sensor is roughly 3K, depending on which variant you have. They up-res it in-camera to 4K. Netflix insists on sensor resolution of 4K or greater.

He told me that Netflix requires a True 4K workflow and that Arri "Upscalled" in 4K. I don't know exactly what the term "upscalling" means in this context. Would this imply that Netflix wants a camera with a sensor with the number of pixels in True 4K. In our case that is 4096x2160, although I see there are other dimensions available in Avid's project choices. I have been under the impression the Arri cameras were at the top of the food chain in the Film world and elsewhere. I've heard DPs who love the Arri's because they are the closet thing to film they've used in the Digital era and I've been told there are a lot less tweaks in the camera menus so the old school crowd are less intimidated with all the menu bells and whistles. I don't work in the field and have not worked with any of the current bread of cameras but I find it hard to believe that Netflix would not allow material from an Arri Alexa. Perhaps the Amira camera doesn't meet their standards but the Alexa, if what I'm understanding from our DP, is also not acceptable.
