I won't lie, that's pretty subtle. I can see it but it isn't terribly obvious.
The reason it's kinda hard to see is that your forcing perspective with those pictures, closer things always appear bigger than farther things in a photo, and you took both photos with the lowered truck closer to the camera diminishing the perspective size difference.
I'm sure with a straight on photo of both trucks side by side it would be more noticeable.
Too bad you won't be able to park it next to mine after the 4" lift.
