Puzzling Export Behavior - Noise Reduction

[Slobodan Blagojevic]

Noticed this for the first time. On the right is the image from the Develop module, after luma noise reduction of +40. After exporting and downsizing, one would expect further reduction in noise. Instead, the image on the left looks like Lightroom "forgot" to apply noise reduction?

Any thoughts?

P.S. Turning on and off Output Sharpening in the Export dialog generates very little difference

P.P.S. These are Canon's latest files, with a .CR3 extension. Is it possible that LR has not been updated yet to handle those? I remember a couple of years ago when Canon's own raw converter did a significantly better job at noise reduction than LR at the time.

Is this a new camera or did it receive a firmware update?  I think LR treats files in a camera dependent way.  Nikon raw files all have NEF extensions but when I upgraded from a D810 to Z6, my current version of LR would not work.  I was still on the stand alone 'old' version which was not being updated any longer.  I had to upgrade to the subscription version (and Win 10 because Adobe did not support Win 8.1) in order to just open the files for processing.  You should be able to query the Adobe support site to make sure the files are supported. 

I just did a couple of experiments using some NEF files and they seem not to have the issue you report.

According to this article: article, Lightroom Classic CC 8.0 is supposed to support CR3. There is other info there that may be helpful in sorting this out.

Does the same thing happen if you export without downsizing?
