That would indeed be a way to test if vcgencmd command works.

Though the problem is its suggested use, not the command itself.

Although you did not mention it, I take it you picked up on that just
disabeling HDMI output doesn't cause my TV to switch back to its previous
input.  Which means that that vcgencmd doesn't seem to be the sought-for
solution (and nullifies the need to test it).
