If there are differences, they usually stem from different editing processes.
Precisely. If you don't edit the file then there's no benefit of RAW. The standard colour space can cram all visible colours into an 8bit JPEG. You start editing though and you want your 12 or 14 bit data so the algorithms have more sample points for their estimations of what the data should be when you slide some sliders around in image editing software.
For instance, RAW has enough data to adjust white balance without loss of fidelity. JPEG does not, you try and bump up the orange channel and you'll introduce colour artefacts in the others.
If you don't edit, don't bother. It's an extra step you don't need to deal with. That RAW makes everything better is a somewhat averagely common misconception. I shoot RAW, I edit a lot.
