Looks a bit soft maybe but this isn't a bodybuilding contest. Muhammed Ali wasn't ripped, Fury is skinny fat... Hrgovic is not anymore ripped or bigger.
He's tubby. Ali wasn't ripped but he was toned and perfectly proportioned for a boxer. Itauma isn't toned or built for endurance.
Itauma has been known for liking the "nightlife" and his weight has ranged a lot in his short career, between 235.5 and 254. That is a comparable range to a young Tyson Fury. Itauma is not the most disciplined, for sure. This is one reason why the "he can come back from a loss, Wlad came back from three" stuff is silly. Wlad was perhaps the most disciplined, obsessive, backside-retentive HW champion of all time. In that respect, he had an elite mindset. And Wlad was able to take losses in his stride without totally losing confidence or the fire being extinguised prior to him being 41. There is no evidence that Moses "I don't even like boxing, I want to make my money and get out" Itauma, who had never lost before and was even more hyped, can do that.
