Is this normal? White vertical lines in EOS 5D Mark IV images

[Paul76]

Started to notice issues on my photos, wondering if anyone knows what it could be or is it something more serious with the camera body?

Canon 5D IV with 70-200 2.8 IS III

Was processing a few photos i took yesterday, dehazed a few and notcied white vertical lines to one side of the image.

Took a sample photo of the current cloudy day, ISO is 6400 (which is when ive started to noticed it), there is a lot of noise, i know, done this to make it easier to highlight the issue.
