Do you spend a lot of time driving an automatic transmission? After putting 150,000 miles on my car, I'm kind of surprised I don't have more asymmetry in my legs.
asymmetry is fine but not able to do a left calf raise is a problem. I do drive an automatic yes.
More likely you favor one leg when exercising, which is common and needs to be adjusted for. Asymmetric atrophy creates a feedback loop which exacerbates the atrophy.
