ARRI looks for ALEXA cameras: ASC CDL values, saturation and the target color space, stored as XML.

Loper is a free, minimal editor for macOS that opens ARRI look file (.aml) instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
