See, that's the pain with blackbox decoders / renders and magic MrMagic. No one can tell you that and you cannot verifiy it. But the good thing is: As long as some green light is shown somewhere, people have the "this is much better" experience in their brain, no matter the picture. Happens for years with audio passthrough ... Perhaps they signal DV, just send "linear constant" metadata and do tonemapping / processing internally :-) - you cannot prove, you cannot know - and when you tune the "contrast" and the colors a little bit more ... subjective impression changes again.
