Just for grins:
SHOT A (Scene File 1)

SHOT B (V-log L)

SHOT B + V-log to V709 LUT

Gee, I wonder if my DVX200 is broken. :|
Why do they look different? Because using V-log is not a flat gamma version of any Scene File. It is it's own thing and so Scene File 1 and V-Log L can't be judged the same way, nor will they render colors the same way. Think of the DVX200 always shooting in log. Now imagine all the Scene File Settings are all basically LUTs applied to it. That's not what's happening, but it's one way of seeing how they should be treated differently. Also, using the V-log to V709 lut is only a starting point...and not the right one for every single project, either. I rarely use it, myself.
ADDENDUM:
I don't want to be the last word after Barry's last word...so, I'm going to answer a question here. Pa-recordz asked "Did you use the internal recorder?" just before Barry interjected. Here is my answer:
Yes. Internal DCI 4K 8-bit 4:2:0. I used my DVX200 completely stripped-down...even used the stock sunhood. I did an initial set on the scene file settings so they were factory-set. Used the "Normal" color tone, instead of the v1.4 one. Handheld with OIS. 12.8mm at f/2.8, ISO 1000, no ND. Cool evening sun through a window with arctic-white curtains. No practical lights. No movie lights. Black-balanced, then white-balanced off the slate (not the white on the clapper). The clapper/slate is leaning up against a Fujinon B4 ENG lens. The dinner tray table is some kind of dark wood, most likely a finished mahogany. There are examples of other, lighter wood colors in the background. The wall is sort of a cream color. As I suspected, the V-Log to V709 LUT made the blues cyan. Why? Because the LUT was never intended for the DVX200, as Barry said. That's why saying "for DVX200" is incorrect, and it's why I rarely use it.
