Ah, but see perceived differences in power, are probably more important than actual differences in power.
It's why so many people held off from buying the Dreamcast and why the SDF vent such fury on 'lazy devs' when the PS3 comes out worse in Face Offs.
If word get's around that all Durango titles look worse than their PS4 counterparts, that's not going to be good - no matter if your average consumer can actually tell the differenc between the two.
That might be true here, in the real world not so much. It certainly hasn't crippled PS3 sales has it.
