I you mean how to capture the PQ signal of a device? Sure, you can do that with any capture card but you're testing the player LLDV this way.
TV-LED cannot be captured since the final PQ image is generated by the TV and not the player.
The shield red push and other content have been tested this way in this thread a while ago( with the shogun atomos). I don't think the multi-pattern ever been tested this way though.
