IQ difference between DNG files generated by DP0 Quattro and LR?

Hello all

I just bought my first Sigma camera a DP0 Quattro and I want to shoot only DNG files.

The DNG files my camera generate in 21:9 mode are about 105 MB each.

I have noticed that if I import them to LR and then export them from LR to DNG the average size of the new DNG is about half of that from the camera. This makes a significant reduction in cloud storage costs over time.

When importing the LR generated .DNG into LR and then comparing them to the camera generated DNGs there is no visual difference to my eyes.

Has anybody any experience with using these “reduced” DNGs and their impact on IQ?

Thanks

AnnaBB
