You can see this same effect with your eyes on some level. I think I heard once that this might be why people associate stars with the star shape, since human eye lens apertures can produce a roughly star shaped bokeh that can be seen when looking at the night sky.

Is bokeh essentially a form of photography art achieved through the circle of confusion?

According to this article on bokeh, https://www.bhphotovideo.com/explora/photography/tips-and-solutions/understanding-bokeh , it is the rendering of circles of confusions that produces bokeh.

(Not related to Bokeh) One interesting effect, which I noticed when taking a picture of street lamp with small aperture at night, is that the light looks starry on the image. The effect is related to aperture blades in the lens, which makes the aperture not a perfect circle. Check out this article, https://www.slrlounge.com/diffraction-aperture-and-starburst-effects/.

In the following short paragraph, I will elaborate on the Bokeh effect. Bokeh emphasizes certain areas in the image and it often appears when parts of the image are out of the focal region. We can achieve this “out of bound” effect by increasing the aperture size (consequently decreasing the f-number). To get “good” bokeh images, recall that high ISOs and long shutter times are often responsible for digital noise. Thus, it may be a good idea to use relatively lower ISOs and shorter shutter times.
