Even with Arab gene flow, Muslim and Christian/Coptic Egyptians are very genetically similar, which shows how small Arab contribution to the Egyptian gene pool was. There is probably a bigger difference between Egyptians in the north vs south, and a much bigger difference between “city” Egyptians and Egyptians in the villages or desert. Across the Middle East, “city” people tend to be lighter, in part due to lifestyle but also often due to genetic differences (e.g. bedouins have genetic distinctions and don’t intermarry much with city folk). Copts with lighter skin are a small minority among Egyptians with lighter skin in general. Not that it matters much, but this is interesting to me from an anthropological standpoint.
