For once I'd actually consider importing the Snapdragon version of the S8 (unless the S8 uses the SD835 globally of course, or the Exynos version is equally specified).
Looks like Qualcomm is not holding back in terms of the ISP features.

It's the same marketing spiel everywhere isn't it?
Doubt you'll see any differences between the exynos and snapdragon modes in terms of camera.
If there was I'd imagine he Exynos would yield better results considering its Samaungs in house processor made specifically for devices like the S8.
