It looks like a typical case of a decoder using the wrong colorimetry. Rec. 601 and Rec. 709 are frequently mixed up causing just a difference like in those comparison screenshot. DVD and Blu-Ray both support both, afaIk. Without analyzing the video stream, it's hard to tell which one is right, though.
It's not hard to tell which one is right - playing the show back through a standard Blu-ray player, it looks exactly the same as in our screenshots. What's more, our screenshots also conform to how the show looks at CBS Digital, where they're doing the actual color correction!
So, no yellow tinge folks. Panic over.
