AMDGPU, if it was actually installed (cough, cough), claims to have a 4.3 GL profile: https://wiki.gentoo.org/wiki/AMDGPU
Yes, but that's when using the core profile, not the compatibility profile. For what it's worth though, there has been some effort to implement the compatibility profile in Mesa recently.
