yeah I'm seeing them also. I'm also seen keyboard navigation enabled for ad.
if you search press enter, then enter again you go straight to the top advertiser instead of the first organic result.
My ad background color is lighter also "it's almost white".. and the ad have a preview hour glass The ad look almost like organic results.
maybe Google is testing for an upcoming change.
