There might be a couple of extra things to consider. So, after the DC explosion, there's a bubble of vapour that's oscillating in diameter, which is causing additional damage to the sub's hull, beyond that of the initial explosion. Seems to me that the amplitude of the secondary oscillations would be a factor in how serious the damage is - I'd assume there's only so much movement you can design for in a submarine hull when you build it, before either it, or the things attached to it, fail, become detached, split, get bent out of shape or whatever else. Now, at greater depth, the hydrostatic pressure is obviously higher. The initial "peak" size of the vapour bubble is a function of pressure (because V = ZnRT/P). So at a greater depth, the size of the secondary osciallations is smaller, consequently, the damage associated with oscillation of the hull will likely be lower. Maybe. Although, if you're already so deep that you're below the your "test depth", I doubt that you'd be very keen to expose your sub to any kind of explosion at all, really.
