It's highly unlikely anyone is going to (easily) replicate what madvr can do. Tone mapping has been in the works for well over a year now. HSTM has taken weeks and weeks of intensive user testing to find the best settings. And that's just one part of what madvr does for tone mapping. (Yes, it's been one of the most dramatic in terms of picture enhancement, I'll grant you, but, it's hardly sitting alone). There's a reason that madvr tone mapping takes so much GPU power....it's because it's doing a LOT to keep the best possible picture quality while keeping director intent. That last part is important. Because while tone mapping can be done by all kinds of different devices, ensuring you don't "overcook" the picture is very important. Personally I want for a day when tone mapping is no longer required and we can watch all this content natively on our 10000 nit displays. Until then, I will be using madvr's exceptional tone mapping. It keeps getting better and better each iteration. The best part about that concept is that the Envy will get each update as things are improved. Fantastic.
