afaik most of the t14 schools really care about their stats. So it is not something that they will overlook and ignore, but you can always add an addendum to your application explaining the previous low GPA and your overall grade situation - how you've grown/improved as a student - which should be noticeable with your GPA change.

I am in the same boat as you, went from a ~3GPA to over a 4, but the LSAC GPA is sitting somewhere around 3.6...
