I don't know that anyone else has noticed this, but in the spy shots where you can make out the headlights, they actually look dimensionally larger over the headlights on the JK/ JKU.
Just remembered reading this article last year on Jalopnik with info from a dealer rep who attended the FCA dealer meeting in Vegas and saw the JL:
"Biggest surprise at the end though was seeing the new 2017 Wrangler. Not a big departure from the JK, but I’d say it shares nothing with the JK."...
Viewing these shots is like squinting your eyes without actually doing so. These shots are super low quality. You can't even visually tell there's the arch in the grille.
