The subtle touch of Jony Ive?

I noticed on the way into work this morning that the audio controls on my lately-upgraded-to-iOS 6.1 iPhone looked ever so slightly different.

Surer enough, as these two screen captures show, they are. Is this the subtle touch of Jony Ive’s new UX leadership in the post-Scott Forstall era? That scrubber control certainly bears resemblance to brushed al-u-min-ium.
