Introducing a test flight with the new livery during the upload will be a good idea because in my opinion this preview is insufficient because, for example, my liverys after uploading (already in the game) look completely different than before the upload.

dense geyser
glad orbit
i was literally thinking of this a few minutes ago, infact there should be an option too where you can interact w the flaps, spoilers and the landing gear
