Not necessarily, Mike. Foe example, they are often found on the earthy side of the brightness control on TVs. They allow the brightness to rise at switch-off to discharge the EHT quickly and prevent screen burn.
I can't find any data for this particular VDR but I have found one with a clamp voltage as low as 14V.
I've no idea just how low the clamp voltage can be, though.
