Significance of Undergraduate Degree Difficulty in Admissions Decisions

I plan on applying to some of the T14 law schools this upcoming admissions cycle, but I worry a bit about my GPA. My cumulative GPA is a 3.90, which is a bit lower than the median for many of these schools. However, I majored in mathematics and physics in undergrad, which are degrees generally associated with high levels of academic rigor and difficulty. I am wondering if the admissions office tends to take into account type and number of undergraduate degrees or if they simply just look at the number and take it at face value.
