The sharp gradient steps indicate that there's no dithering. Dithering attempts to increase the apparent colour depth by error diffusion or adding patterned nosis.Upclose,and with contrast added dithering typically looks like noise. When used well it can drastically increase the quality of gradients. Core Graphics dithers gradients,so that makes it unlikely the button was drawn with code or created using a tool based on Core Graphics. It also rules out PDF assets and toher Core Graphicls rendered paths. The button almost certainly had to be created in Photoshop,which can optionally disable dithering,or Illustrator,which has no gradient dithering. We can also see that the gradient steps are evenly spaced _the gradient uses linear interpolatu8on. The defautl for gradienst in Photoshop is for spline interpolation, rather than linear interpolation (the smoothness setting in Photoshop controls interpolaton).
