"Cold Case" is the program I think you mean. It's still on as reruns. You are right about the look although IDK if it was shot as digital. Whether digital or not, I think the look was intended to help communicate the cold, gritty atmosphere of Philidelphia, many areas of which I would describe as "cold."A few years ago there was a network TV crime or FBI show (I never watched). Can't remember the name of it.... But I think it was shot in digital and it always had a blueish, cold, contrasty look--just awful. No saturation.
