By default, sure, for people who don't know about these settings, they are setting themselves up for failure when a few numbers get transposed. They should ship the device with highest quality settings so your customers are impressed out of the box, instead of being disappointed that they have to tune the device to get a high quality copy. If you must save a few bytes in this age, then you can turn on these crazy settings as you like.

I can just see a legal loophole now for anyone using these devices, for example "the electronic document was modified by a Xerox and we don't have the original, those numbers were not what we signed, contract void".

No matter the case of an optional setting or the size of the font involved, this can have major consequences for people who trust the device to be an accurate representation in all cases, of what they put into it.
