I would take his dose down. When an acro/IAA kitty starts to look all flat and green, it's often the sign of a dose reduction coming. Unfortunate, as he was looking really good on this dose. But maybe just a 0.25 unit reduction will keep him that way.
You could be right on the possible IBD flair, they can be nasty. And p'titis is often a companion with it. Though it typically raises the numbers. Hope the vet calls back soon.
