Doesn't the Hobbiton example demonstrate that a constant green was not accidentally cast over the entire film, but instead that whatever differences exist were intentional?
Based on having analyzed lots of frames from the movie by color samples and comparing, I'm almost sure they first made a re-grading of each scene and some overall color changes, then the green cast got added on top of it.
For example, aside from the green cast there's a lot of parts where grey and green colors from the theatrical are instead blue or cyan. Some blue colors are darker overall, and some green colors have been shifted a bit more towards cyan, making for example forest trees look neon-like. Some red here and there have also been shifted towards yellow.
Funny how we are so off-topic here, sorry! :)
