Not sure what kind of support AME has for ARRIRAW files. You might be
better off with Resolve Lite (up to UHD) or ARRI's own ARC - ARRI Raw
Converter. You want to end up with a LogC image at the correct white
balance and ISO -- extracted from the metadata or can be corrected in
either of those tools.

LUTs are built for specific parameters, I wouldn't expect just any LUT to
work on something it wasn't built for. You could build a "more correct" LUT
on ARRI's website, if you know the parameters on how it was created and
what you need to output. But saying that, if this is just for viewing your
composite and not baked in... eh... you might be fine.
