After Level Up the portraits don't look like before but similar to what they looked like in EA. Just a frontal shot of the character and not even centered.
(Steam version, Patch 8)
I posted a thread on this one on here (and on reddit).
According to some, this is not new behavior - but I sure thought it was as I had never seen this happen on any of my play-throughs and only ever saw it when I was watching patch-8-stress-testers' YT-streams of a pre-release candidate.
