Or am I missing something here?
it 'should' be, as long as that device doesn't alter anything.
the only 100% guaranteed method is to play back the test patterns on the same device, the same way you'd watch media(ie, a bluray test disc on your bluray player. But, as long as your device doesn't have any settings, or in some other way alters the signal, then yes, it won't matter how you play the patterns.
to give you a real world example of when it can be a headache, when I calibrated my display, I originally just played the avs patterns off my htpc. but I suspected my video card settings may not be 'right', so I loaded up the test patterns on a usb and played them off my ps3. what I discovered was that the ps3 clips whites when playing off a usb, so I really needed to burn the avs patterns to a disc, and then play the disc off the ps3(my bluray player). then, after calibrating with the ps3, I could then adjust my HTPC's video card settings, so that it was also accurate. my cable box, which does not have any options as far as I can tell, looks 'right' but I have no way of actually checking.
so again, what 'should' happen, and what does happen, may not be exactly the same. I was surprised that the ps3 would playback content off a usb differently than off a disc. but I think you start going down a slippery slope to insanity if you start worrying too much. even when I used my HTPC with 'incorrect' video card settings, the calibration looked good with the ps3, my cable, and all my sources. even though it was off, it wasn't by much
