I mean, you genuinely believe that it being on consoles will make the PC version look worse. That's really something.
In terms of large-scale development, it can have an impact.
2/3 of the platforms they're developing for are under-powered APUs, but they have the exact specs on those machines and therefore testing is easier since there's no variables as far as hardware and software. It's likely most developers therefore target lower-spec machines first and try to create models and textures with low enough draw-calls inengine in order for those machines to run.
Creating high detail requires more artists, more money and more time. It's easier for a publisher/developer to target mid-range and lower their losses and then have everything touched up during trailers than it is to spend years making everything beautiful and optimised for PC, and then scale it down for console.
