Well it would be appropriate to have at least a notification of the type of ilda file. Most users would expect the oldfashioned-8 bit-color-palette-ilda when ilda export functionality is mentioned.
Some demo-users might be disappointed of the output files, and refrain from buying the package.
I currently have 3 mono-colored laser so don’t really need 24-bit color.
Old fashioned ilda output would be welcomed by me, and many more mono-colored laser owners.
I even think a lot (most?) of your potential customers don’t even have full color.
Well, we all have full-color dreams, don’t we ? 😉
