I believe they increased the density of the eyelashes across the board with 'longer' shape at the edges. It gives a fake lashes/heavy mascara look, while the eyeliner on the upper waterline + eyelid increases that effect.
The old one had no eyeliner and the lashes were abit more sparse and somewhat evenly spread. For my eyes at least.
Here's another slider from face on view. You can see it abit more here I guess? The angle is abit off though so they're not lining up well due to the character breathing ahaha
