X-T2 Noise at low iso, should I be worried?


I recently purchased the X-T2 and love it so far. Today I shot some photos of some kitesurfers with the XC 50-230 and whilst processing them I noticed that even at iso 200 I can see the noise from the file. See example below, exported out of lightroom with 0 edits made.

Should I be worried about this? or is this completely normal?
