And that's a downside to the wide aperture. You can see more, but you can lose a lot of detail where it matters. Especially pet fur
I noticed that a lot with the S9, but not so much with the Note 9. I think they have addressed that to some extent with the Note 9, based on most of the pictures I see on this thread vs the S9 thread.
I don't think any reduction is detail is because of the wider aperture or because of any smoothing algorithm. Instead, the S9 and Note9 tend to use faster shutter speeds than the earlier Samsung phones (presumably to reduce motion blur). This results in higher ISO, which requires more noise reduction in low light.
I find that if take pictures with a slower shutter (with the 1.5 aperture), more of the details are retained than I had with the Note 8.
