P: Poor photo in the library and develop module - smart previews

I have a problem with version 10.0,
the photo is of poor quality in the library and in the develop module. I use smart previews (the disk with the original photos is disconnected).
smart previews in version 10.0 have poorer quality than in version 9.4
When I install the older version (9.4), the same photo with the same preset is of better quality (also smart previews).

It looks like there is a higher grain in the photo
Here are photos exported from smart previews.

Tested on: Mac pro 2013 (6core, 16gb ram, D500)

Macbook Pro 2014 2,7 ghz 4 core, 16gb ram

 

10.0:

9.4:

Photo exported after attaching a disk with the original photo:

    I don't see any zoomed in option.

    This could be a similar issue discussed here:

    Like there, this OP should provide a DNG with all the edits and upload for others to examine. When I did so, I was able to generate previews correctly.

    I thought the same until I zoomed in with my browser.  Take a look at the bride's skin.  It's significantly more textured/grainy in the 10.0 export, just as the OP describes.  Once you see it you can spot it everywhere in the image.

    Also this goes beyond mere viewing in a LR module.  These are exports from the smart preview that show significant differences between 9.4 and 10.0.  That is reasonable cause for concern.

    They all look nearly identical on my browser. 

    The only accurate way to view this image data is in Develop, at 1:1 or greater. All other modules use a different preview architecture and zooming out is always less accurate due to subsampling. But again, all three posted images look the same here.

    Sorry, i don't know what you mean. If i save a raw in PS i have a tiff.

    You could have a TIFF if you click Open, I don't want that, I want you to SAVE the edits from ACR using "Done" then examine the raw in LR after you ask it to update the metadata.

    So it is OK in Camera Raw after a second. If you apply a tiny edit in ACR, click ”Done” then examine the same raw in LR AFTER using the update metadata from disk (to update that new edit from ACR), how does it look; match ACR?

    Sorry, nothing is solved. My failure. It's all the same, except that LR opens the DNG monochrome and not colored like the other catalog

    but it seems the problem with the color/bnw is solved here

    Solved how? Sorry I'm not sure what's now going on although I am happy to hear something is solved.

    Done. If i use grain on this raw, it's the same like in the other catalog.

    The picture (dng) in library is monochrome (not in color like the other) but also bad. 

    Try one more thing; import the original raw, not the DNG into this new catalog.
