How to convert tiff scans from a lab

I’ve been using NLP for a while for 35mm, but I don’t have a scanner for 120 so I’ve been having my lab do positive tiff scans, leaving the film unconverted. They are using a Naritsu scanner, and when I asked about the gamma settings they didn’t have an answer. The conversions I’ve done so far have been ok, but I’m wondering what the best practice is.

Should I be using the tiff scan prep utility?

Does anyone know the native gamma settings of a standard naritsu lab scanner?

Thanks!

You might find some technical information about gamma in the file’s metadata, or could share an image or two on a cloud/sharing platform like dropbox or swisstransfer.com for us to check the files for you.
