I thought I'd do a comparison shot from P3D. Same height and time of day/year, lat and long is slightly out as is the viewpoint location but it's the best I could do without spending all day on it.
I was impressed with the accuracy of the coastline and associated structures....the problem with the sea colours is probably insurmountable for FS developers and I do understand the issues. In reality it never looks the same on any two occasions, wave height / direction, light angle / level variations = too many variables that make a massive difference to how it looks.
