There may have been regressions, but if you look at the RX 480 benches after the initial performance patches to Deus Ex: Mankind Divided the RX 470 does way better. On low settings at 1920x1080 the 480 did 36.30 FPS when the 470 now does 58.10 and that's pretty much the same performance figures the R9 Fury did. These new tests used "high" rather than "ultra" settings, but even with high settings the 470 performs better than the 480 did on low settings (45.50 vs 36.30).
Here's a link to Michael's tests just after the performance patch:

do those benefits translate to all GCN GPU or polaris only or 470 only?

Memory management improvements might be responsible for this, but I'm not completely sure.

Whenever you see an improvement like that when there haven't been any major changes you should probably actually look at the images being produced. I get the feeling that there may be a bug somewhere and some part of the render pipeline is being skipped. Maybe anti-aliasing isn't working?
I remember that a few years ago Nvidia got caught cheating in game benchmarks by having the drivers override the anti-aliasing settings to something less taxing and blamed a bug when people found out that if you changed the name of the .exe file the game would actually use the correct anti-aliasing settings and as a result run slower than if you didn't change the name of the .exe file.

The game works fine for me with the 4.8 kernel on my rx470, It must have regressed with 4.9 or 4.10.
