I think the screens you've shown are maybe Map and/or Firmware rather than Locale dependent in this case. Typically with some modern Garmin units using an EU map will get you the top appearance and with an NA map the lower one, but then changing the Locale will reverse it with some maps on some units (e.g. AU NT mapping on some nuvi 2/3xxx can change appearance depending on Locale set and even varies between models [fw has some influence also in that case] and will have either the round or rectangular SLI and corresponding blue or green top banner). But i really have no idea with Kenwood units if it works only with NA/EU mapping data type or it's fw or both, however naturally it can't be Locale influenced as that can't be set.

If you're brave, you could maybe try cross-flashing the NA model firmware but there's a very real risk of bricking of course. It mightn't help anyway and for sure won't if the appearance is solely map dependent. Or just change the map to an NA NT to see if appearance changes to confirm/eliminate the map influence.
