You cannot sustain this kind of NR throughout the film without some serious DVNR side effects due to tearing and motion compensation errors.
Well to my eye the de-noised frame looks “plasticy”. I suspect it’s because it makes the out of focus objects appear to be more in-focus than they should. That said it has completely stabilised the chroma, which is one of the many issues with the official Bluray and also an issue with the SSE. So if you kept the chroma, and optimised the settings for the luma it should look really good.
