A decade or two ago I remember an experiment where canned food was presented in a restaurant setting and people couldn't tell it apart from the hand-hooked. The presentation was what mattered, as long as it didn't look like it was canned/frozen then they thought it tasted like restaurant quality.

In many cases canned food is a lot closer to fresh than frozen or instant would be.

In any case, those are ingredients (analogous to...libraries I guess?) and not to the whole application. If you served someone a canned sandwich or canned sushi or some such, they'd notice.
