I do notice what appears to me to be a slightly greenish LCD background tint in the 15CE in front of me, however I happen to be one of those who prefer it for reasons below.

This discussion is reminiscent of the comparison between the slightly greenish 49g+ LCD background to the slightly grayish 50g LCD background, where some have commented that the 49g+ screen appears slightly brighter and easier to read, and is true for me. Holding the 15CE next to the 49g+, the slightly greenish LCD backgrounds appear similar.

There are two reasons that might account for the better readability of slightly greenish LCD background tints: (i) they may be more reflective so appear brighter; (ii) the the retina is most sensitive to the yellow-green portion of the EM spectrum (an evolutionary adaptation to the same region of the spectrum that solar output is greatest) so the contrast is better for the human eye (though bees may disagree with peaks not only in the green but also in blue and UV :)

Bottom line: If there is a slightly greenish LCD background in the 15CE, any slight advantage in readability and contrast may actually favor it over slightly grayish backgrounds, at least for some, especially if reflectivity and human eye spectral sensitivity are taken into account,
