is this normal

[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.

Share some raw files instead.

How?, CR2 files are not supported to upload

You can share a link to a reputable filesharing service like OneDrive, Google Drive, DropBox, etc.

Is it present BEFORE you applied the noise reduction to the images? 

[Paul76]

It was a few white stripes running down one side of the photos that I noticed first, did the dehaze to the max to highlight the effected area

Your posted image seems like it is a tight crop.  It lacks context.  This is why others are asking to see a sample.  So am I. 

[Paul76]

do you notice the dark lines down the right side, from top until half way?

[Peter]

Yes. Share a couple of raw files.

I would like a raw sample with a shutter speed longer than 1/180 sec, preferably towards the sky. This to rule out the shutter.

I would like two pictures of a white wall inside. Exposure longer than 1 second for both, but one with Long Exposure Noise Reduction turned on and one without. This to see if a dark frame will remove it.
