No they don't. They look like a shitty replica of them made by someone who understands nothing about art. Just because they both have "gradients" means nothing. iOS has smooth 3D gradients. These have a plain and awful looking linear gradient from top to bottom with two colors. The messenger one you linked has so much detail and personality. These ones have neither. They are, as mentioned above, like cheap Clipart. If you honestly can't see the difference between the one you linked and these new Android ones, then I don't know what to tell you.
Oddly Facebook Messenger seems to have the best set [1], for my eyes.
