A few from the State Art Gallery of South Australia, taken last week, and all using the inbuilt camera app in either HDR or Portrait Modes.
These were all taken using HEIF as the image format, and I did no editing to them, they are straight out of camera in all regards. I simply exported them from Photos with no tweaks applied. I do love the colour rendition as it is, and feel absolutely zero need to play with editing anything in this regards. I work from a 27" colour calibrated iMac and my colour judgements are made when viewing on this, not when viewing on my phone.

In HDR mode, and the skies are still blown out with no details at all, at least there's good shadow details!
In Portrait Mode.
This is my favourite sculpture in the art gallery, and Portrait Mode did a smashing job on defining the edges of this piece to apply the background blur really well. Except for the section between the legs of the character on the right, where it used part of the image from the wrong lens on the the edge of the floor and architrave here, resulting in this bit being higher than it should be, and it hasn't blurred this edge either.
In HDR Mode.
Even though the definition looks good at this size and resolution, the details to this material are considerably soft when viewed larger. (I think that the noise reduction is applied too heavily and this results in the softening of what should be otherwise crisp details.)
In Portrait Mode.
With the ISO at 800, there's quite a bit of noise in this one and the sculpture doesn't have the super crisp edges I expected it to have. I think that's as a result of the algorithms being applied in Portrait Mode and it not knowing exactly where to apply the blurring effect.

A tricky one for it to deal with and I think it did a superb job here!
My final thoughts are that it is very much a beta feature and Apple are still calling it that for a reason. I believe that they will fine-tune things along the way, so that it only gets better with time. But, for now, be prepared to have hit-and-miss results and take numerous shots of the same thing/people/person so that it hopefully works well in one of them!
