Depends on how long its been since you had it running and the ambient temp. That temp is normal for most engines if it has been within 4 hours of starting your truck and it is 90°F plus degrees out. It is not normal if the truck has been sitting all night.
As others said, temp readout starts at 122. Anything less is <122 and that's it.

Mine reads 100 dead cold. When it goes to 104, i know there's heat in the engine and off i go
Thanks for that. I’ve got a 2018, 6.7, it reads 104 cold and it isn’t addressed anywhere in the manual. I’ve been waiting till it hits 105 to drive figuring that was the minimum.
Likewise. 2017 6.4 always reads 104 at startup. Trans temp reads ambient temp. Was 2 yesterday.2016- hemi 6.4-- reads 104 always at startup
