[ELI5] Why can’t we access the whole colour gamut they show on the graph? And only portions like sRGB?

So, I’ve recently started to learn about Display technologies, and I’m having countless questions.
How are able to use 8-bit per channel displays and not run out of system memory?
There must some amount of compression right? Where can I download a true 24 bit image with 1 bit colour occupying 1 bit memory?

Simple answer, math and the lack of any device currently available that can even reproduce the colors. The more colors defined in the gamut the more powerful the device required to calculate and reproduce the colors. Technology hasn’t reached that point and may not ever. We’re talking about basically infinite amount of colors that can be defined by many different parameters(hue, saturation, luminance, etc). It may also be because of diminishing returns. The currently available color space standards are sufficient enough to reproduce most images with good accuracy.
