There is some basic info on the vehicle and its payload at [1]. "The spacecraft will also carry a color camera, called JunoCam, to provide the public with the first detailed glimpse of Jupiter's poles." - so like you say, not a priority. More on JunoCam at [2].
This photo was taken from 2.7M miles, and Juno will approach closer than 3,000 miles of the cloud tops, so you can expect the resolution to get roughly 9 thousand times better.
