Hello. I been trying to read alot and look up things so i dont try asking something i can easily find. In the guide it shows a description for the mode options but it doesnt describe what each of them do or when would be best used for. Sorry if this has been posted somewhere. I just wanted to get a better understanding of each of these options.

We don't really define any specific use for any of them...

However, some are specifically for verification/evaluation, and not really for LUT Generation.
And the + sets enable the Multi-Primary Colour Engine: https://www.lightillusion.com/advanced_operation.html#plus
