Although, I gather (according to one review) the HD 100 is about a stop faster when in DV mode as against HDV mode.

I am glad you have commented on it being unusually fast because that's how I felt, and when discussing it earlier with someone they were suprised I was so confident getting away with it in such low light compared to the Sony Z1 (so much so I needed second guessing in case I dreamt my experience )!
The budget won't stretch for a 2K (which I always like to have around) so I need as much stop as possible using 500-800w lamps with white balance correction. I was confident after the tests so thanks this is reassuring piece of mind.

Using the two cameras, the Z1 seems to have more aperture ramping than the HD 100. On the surface, I wasn't aware of the HD 100 stock lens being any worse in this regard than your average ENG lens, whereas it's extremely noticeable on the Z1.

For example, in "normal" gamma I typically rate the response at 200ASA.
However, you can increase the response to as much as 800ASA by maxing out the gamma.
I performed a test last year with the gamma set to MAX, gain on 0dB, Black Stretch 3, 1/48th shutter, and only available light at night (approx. 2 footcandles ambient, 5fc in the hotspots)
