I have enough experience with news outlets to be able to confidently say that news photos are calibrated in a very odd way that maximises how the photos look on a very broad range of monitors. Do not judge anything about your screen from news photos.
Is your screen calibrated? Macs do not have internal calibration, and drift a lot over time. Get a calibration device and calibrate your screens if they aren’t, particularly if you want to print. A calibration device costs about 1% the cost of a Leica M11 but is vital if you want to make good output from that, or any other, nice camera.
