That extra bit of accuracy may be worth throwing a little off anyway, if you don't have the NVIDIA settings that is, for the mentioned benefit of added contrast. The alteration ended up just being a minor boost of Red and Green in the monitor settings in ratio to the Blue and then further compensate therefore a little bit in the NVIDIA settings (to be able to produce a higher level of contrast).

However, in this case, it was worth it to balance out one of the inherent flaws of the monitor and make up for it more with the NVIDIA settings. I typically try to calibrate the monitor to its furthest accuracy, or otherwise full potential, before I proceed to making any adjustments in the NVIDIA Control Panel (or any other drivers/software for color display calibration). There's a lot I could otherwise say about this monitor, but I'll leave that out unless directly asked about them.

So I've been fiddling around with the monitor settings for a while and I feel I've come up with a result which I think can now be considered final.
