There's no difference between Mercy now and Mercy 10 years ago. It's been rumored that the Nanobots that she uses to heal people has also prevented her from aging. She just looks younger in that picture because it's a different art style and a lower quality image. Basically, every picture of Mercy that you see here *is* the Mercy in that picture, because they'd have the same appearance.
