[MrMagic]

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.

Exactly my point

I haven't searched for it yet, but it would be nice to have two sample files that have the same content, where one is encoded with HDR10 and one with DV and where you can actually see a difference between the two. Does anyone know of such a thing?

I think someone mentioned you could check the signal that comes out of the Shield (or any other box) with an HD Fury to see if dynamic metadata is actually being used? If anyone with this kind of setup is reading this thread, maybe we can analyze this a bit more...
