The way I used to demonstrate the difference between 8 and 16 bit color depth to students was to display a photo on a monitor, and switch between 16K colors (8 bit) and millions of colors (16 bit). I'd ask them to guess which was which. No one could tell the higher vs. lower color depth.
I would then create a white-to-black gradient in a drawing program, and display that in both modes. Everyone could see the banding in the 8-bit color depth.

My question however is, since it is still 8 bit per colour, is the Jpeg file still really limited in fine colour delineation because it is limited to 256 discreet shades per primary colour?
In one word; yes.
