Looks like some icons objectively became harder to recognize: there used to be icons with a special shape which makes them stand out, the new ones are all square using color as filler. The brain's visual system uses both color and shape for decoding, now part of that is gone. They do look more uniform though, but I'm not sure if that is better. After all if you present a collection of buttons the end result should be the user finds the one needed as quickly as possible.
