The iPhone camera app does a lot of those things. The blur is definitely not a Gaussian blur, you can clearly see a circular aperture.

The blurring is also a function of the distance, it's not constant.

And blowouts are pretty convincing too. The HDR sources probably help a lot with that. They are not just clipped then blurred.

Have you ever looked at an iPhone portrait mode photo? For some subjects they are pretty good! The bokeh is beautiful.

The most significant issue with iPhone portrait mode pictures are the boundaries that look bad. Frizzy hair always ends up as a blurry mess.

The Adobe one has a pretty decent ML model for picking out those stray hairs and keeping them in focus. They actually have two models, a lower quality one that keeps things on device and a cloud one that is more advanced.
