In 4.4, kendy reduced the size of the ruler which made it look nicer, but gray color of the measurement numbers which have gotten smaller are now harder to see, so it would be good to darken them.
From my point of view it could maybe be a little bit darker, but to be sure I would need to see them side by side.

Too much contrast is bad as it draws attention to this control. I can easily read the numbers. So this is a WFM.
Rather than a WFM, believe Caolán's work on bug 90214 provided a mid-contrast shadow between darkshadow and background theme color that has been present for some time now.
