It's not anyone's monitor. The entire thing has a blue tint, seemingly by intent of Pelikan since the old version was different. For example, the white point of act 1 is cyan (approximating to 55ddff). The speculars BlobVanDam mentioned ("specular city") come from both back-left (as seen in the mountains) as a cyan specular, and from front-right (can be judged by the specular on the ground leaves ) - as cyan too. The environment color is blue and the two sources of the specular are cyan. The specular is still cyan even in the other two acts.
