Cold Start Idle Haze - Thoughts

Cold Start Idle Haze - Thoughts
Hello Everyone,
Background:
For the past 6 months my truck is no longer a DD, and i mainly use it for the weekends or trips that require a truck. My truck can sit between 1-2 weeks before being driven, and I am now very good at giving it the once over before starting up (check all fluids and overall health). Upon startup, it always idles for 2-3 mins, followed by 1/4 throttle- about 5psi boast til first thermostat open.
Concern:
I have noticed as of late (maybe just paying close attention) that after starting, i am getting a slight haze for 3-15 secs after start up. I get the initial puff, followed by this light haze then clear. I tried to video the haze, but it wouldn't show up on video (have to view from an angle).
I use PS every fill up at the recommend amount, truck always fires right up on a half crank (even in 32* temps), idle/revs smooth, no knock and never smokes/hazes besides this first time start up after siting.
I am thinking its either a sign that injectors may need to be addressed in the near future or my grid heater is on its way out.
Thoughts?

What color is the haze? I drive mine every day 90 miles round trip to work. Its been at 10 degrees when I leave work and it stays plugged in the whole. It also is idling at about 1400 RPM. I also have a haze at initial start up. Clears up in a minute though. Its common for cold weather. I'd only really worry bout it if it would continue while driving after warm up.

When I use to DD it, I never noticed it but now I am starting too. It has only hazed 2 out of the last 5 starts, which lead me to think it was starting to show signs of a part being worn. Something to do with the extended time it sits.
Average temp for the last 5 starts (roughly 2 weeks in-between drives)
- Night = 30's
- Day = 40-50

The grid heaters on our trucks will engage below 69*. So if you think about it, they're designed to activate at that temp range because even that is just not what a diesel engines likes. 30*-50* is right in that relm for the grid heaters to turn on for 10 seconds.
It could be the more you're looking the more you're noticing. It could have always been hazing in that temp range. Sort of like when you work on your truck and then during the first test drives you might worry yourself because you may hear a bunch of "unusual" sounds, when the main reason you've never noticed those sounds was because you never payed that much attention before.
Colorless haze is completly normal
