Well I think the benchmarks show that there's quite a bit of nuance to it. Reflection generated code to get a property's value from its get accessor ends up 8.82x slower than what RyuJit does, because you're stuck with a method call rather than method inlining. ("GetViaProperty" is just reading from a field.)
That doesn't mean you can't reflect even more and get the backing field and generate code to access it, but now you've got your optimizing compiler hat on!
And even then, I think you still can't get 1:1 performance because you have to call the generated method vs. having it inlined.
