I’m skeptical. I see a lot of detail in the results not even present in the original image. Also not sure why blurring and sharpening operations would be changing the color. Is there some temporal smoothing going on as well, which is getting rid of the compression artifacts? Or are the “before” images not a true representation of your source?
A lot of denoising operations have an option for reducing color noise, it looks like some color has been lost through such a method.
It also looks like the algorithm is mistaking a lot of the shadow detail for noise and erasing it, seen most prominently in the doorway to the right and in Anakin’s hair.
