The other item you listed is a slight increase of air temp caused by compression. That's just a fly on the puckey.
I still maintain that the air charge temperature will increase for the same reason that the EGR will lower temps. Of course, I am just going by what I've read and what makes sense to me. I wish I could get some concrete numbers. I'm okay with being wrong, but in this instance I will err on the side of caution.
