I doubt it. Orange is being used because it contains no blue, and blue is supposed to interfere with sleep. Personally I doubt that removing blue light on an ereader will improve sleep but a lot of people do believe it and that makes it worth adding the feature to avoid blue.
Green light does contain a lot of blue so there's no marketing gain from offering it.
I'm not sure this is related but I remember in the early days of monitors when green screens and amber screens were the options our company bought green screen monitors and we had a lot of complaints about eyestrain. A bit of research found that that was a common problem with green screens so we bought a bunch of amber monitors and gave them to anyone who wanted them, including me. It made a lot of difference. Complaints about eyestrain were drastically reduced. I had a lot of eyestrain problems with green screens and hardly any with amber monitors.
