Sure, but to be perfectly honest I kind of doubt someone would be willing to throw $160 on top of whatever HDMI mod they might use for slightly better quality vs emulation on retro consoles. I mean, the UltraHDMI for the N64 alone costs $160, the GC one costs $150. PS1 and PS2 have a cheapo cable, sure, but quite frankly I doubt there are a whole lot of people playing PS1 games on a PS1 anymore, and PS2 is a maybe, but even then I don't think these particular enhancements would be enough for someone to drop a whole $160 on these days.
Hence why I said the main audience would be 360/PS3/Wii U, they're really the only consoles that, at this point, could really benefit from an external device that could enhance their visual quality that can't already be done with emulation (that also wouldn't cost an arm and a leg for an HDMI solution along with it.)
PS4/Xbone are laughable, quite frankly that's just marketing BS to trick the clueless into buying their device. The "enhancements" this could conceivably apply would probably be incredibly minor to the point of being indistinguishable to the average person. The Switch is the only thing this gen that would really benefit from this, since it's a potato compared to the other consoles.
Also, DVD and bluray players? wut? Nobody in their right mind is going to spend $160 to minimally increase the quality of their movies
I mean, Bluray players already have built-in upscalers in them (that are better than shitty TV upscalers), throwing some basic filters at them in addition isn't going to be worth a $160 device to the average person who actually still watches media on physical content (which is dwindling incredibly fast, because of streaming services).
