P: Metadata > DNG says denoised DNGs don't embed the original raws

@johnrellis  I am going to let the CR team comment before demoting it. 

@Rikk Flohr: Photography, I no longer think this is a bug but, rather, confusion caused by the ambiguous use of the term "embed" by some posts in these forums. The Metadata panel is accurately reflecting the contents of the Enhanced DNG.  See here for details:

Sorry for contributing to the confusion.

To add:

I just tried Ehnance to apply Raw Detal: no original embedded into the DNG. Same size as the original.

I then tried Super Resolution and again, the size is 3X, making be believe there is no original embedded into that new DNG. 

Adobe, this is a bit messy. I'm not sure the 'concept' of embedding the original raw into (only?) Denoise was explained and there needs to be an option to not do so and of course, an option to remove that original. 

Up voted on your bug report and asked there:

To Adobe:

1. Is the DNG converter supposed to do this?

2. Why isn't such a function offered in Lightroom Classic? And Adobe Camera Raw. 

3. Do users even know that the original is embedded into the Enhanced DNG? Why not state this in the Enhanced dialog? 

4. Better still, offer a check box "Embed original into DNG" so we can disable this. I'm keeping the original; I may not want the original also embedded into the new Enhanced Linear DNG. 

I'm thoroughly confused -- yesterday, DNG Converter was extracting the original raws from denoise DNGs for two cameras but not two other cameras. Today it's not extracting from any of the DNGs.  I submitted a bug report here as a new location for this issue:

https://community.adobe.com/t5/lightroom-classic-bugs/adobe-dng-converter-doesn-t-extract-original-raws-from-denoise-dngs/idi-p/13756277

Maybe I'm hallucinating in some way.

No idea if it's a bug or not. Until this week, I didn't even know the original was in there. 

I've been watching with interest here. Do we think we have a bug on Original extrication from the Denoise DNG or not? If we do we should probably make it a new thread. If you have a file you want me to test, send it over.

I tried again with a proprietary raw not converted first, and can't extract the original so yeah, either a bug or the converter isn't built for this. But this functionality should be within, at the very least, Lightroom Classic, if not Adobe Camera Raw too. As Rikk is here, I'll wait to file a bug report and see if this is on Adobe's radar or not. 

Also, in the Enhance dialog, there should be some indication for the user that the original is also getting embedded into the new Linear DNG. 

I just tried sample 5D MII and R6 MII raws: Denoised them to DNGs and ran Adobe DNG Converter.  It refused to extract either raw.  Seems like a bug.

It worked with two denoised DNGs, one from a Nikon Z 9 and one from a Canon EOS R6.

By @johnrellis

Very odd.  I tried this with a 5DMII and an R6MII, and neither worked. 

I'm on Mac. The latest version of the DNG converter. 

But this may be part of the issue (a bug?), all my raws get converted to DNG in LR from import. So a DNG to Linear DNG, could that be it? Are you creating the Enhanced DNG from an original raw?
