What could be the cause of this blur on every picture?

I’ve gotten the “blur” when taking pictures in the Rainforest from extreme moisture trapped inside lens. Also on occasion when going from a warm house to take a picture outside where it’s very cold, but I could see the moisture or condensation by looking at the lens.

It's definitely not on the sensor - it would be black or dark. A smudge on the rear lens element gets my vote.
My vote too.

I noticed that it is only on pics at that location in the studio. Im thinking a strange light issue. I have checked lens and sensor all seem ok. I wonder if the light hood would have helped. I will have to wait till the next shoot to experiment. Thanks all for suggestions. Btw i love the d750 and 24-70 2.8

Shoot a mono color wall to see sensor stuff- lens can be out of focus- in fact its better. Why better? because you are looking on the sensor, - it will not be dependent on the lens to show up. Your problem does not seem to be sensor related.
Mount any other lens, if no access to one- go to a store , pretend like you are purchasing, ask if you can mount it on your camera and take a test shot... if clear, obviously its in the lens.
Hold the lens up off the camera at various backgrounds, light levels, in either direction and look carefully. Concentrate on the internal elements on that zoom lens and hope there isn't a fungus in there that has etched the glass. When you zoom, ( depending on lens design) the space you create in the lens has to come from outside air, you inadvertently may suck in certain fungus microbes. If stored in a dark, moist place, these can grow, and they attack the coatings and etch them. You have to send it in and pay a lot of money to get it fixed..:(. wanna know how I know??)? One way you can kill these microbes is set up your camera on a tri-pod and place in sun- so direct sunshine is entering lens. You don't have to take photos.- you just want the UV waves to kill the little bastards.I sincerely hope it isn't this- but am worried it might be.

Yes. Dirt on the sensor will shade the pixels from light, it will appear gray, dark gray, or black, not white.

Looks to me like a smudge on the lens, like a dried up water droplet, I always inspect my front glass, after removing the lens cap!
