After testing and looking at monitor specs I have determined that the gamma level is 2.2 (I didn't touch that while calibrating via the Windows calibration tool).

I've heard some people say that the output gamma should be set to 2.4 for movie content? This tends to darken the gamma bit from 2.2 and seems to either improve or over-darken the picture. Not sure what to conclude on that. Any tips?
I'm not really an expert on calibration stuff. If you know how the Windows calibration tool has calibrated your display and if that calibration stays active with madVR running, then set it to "This display is already calibrated" and enter how Windows calibrated your display. If you don't know that, set it to "Disable calibration controls". Or if you have a meter, you can use yCMS for calibration. Gamma 2.4 is for batcaves, meaning you should have black ceiling and walls and total light control. If you have ambient light in the room, Gamma 2.4 will probably be too dark, and the ambient light will eat the shadow detail.

Ok, but what is the source filter? In MPC-HC right click on the video, click on "Filters", then click on the source filter. That's usually the one which shows the source file name. Then copy the text from the "Pin Info" tab and post it here.

Is there an API available to control the wallpaper changer? I'm not aware of such an API. If there is none, there's no way for madVR to disable it.

Not for now. This is one of the things which yCMS 2.x is supposed to fix. I've been in contact with the yCMS developer and he might start working on yCMS soon.

This option will stay, and it will stay enabled by default.

If you're interested in having the problem looked at (and fixed, if it's a bug in madVR) then yes, please.

Yes, by updating to the latest madVR v0.83.

Both these options will be gone in v0.83 because they're not needed, anymore, thanks to the latest NVidia driver.

I’ve seen you mentioned Dideé's "fine sharp", which to my eyes is the best around (better than Seesaw and LFSMod), do you think it will be possible to integrate it into madVR via pixel-shaders (GPU) so that we can sharpen AFTER resize with madVR?

It will be also cool to integrate into the interface the most common pixel shaders and to be able to tweak the basic parameters directly from madVR interface (like ffdshow does!).
I do plan to add support for custom pixel shaders, and there will be different shaders for before and after scaling. I can't say much more right now, though, because I haven't even started working on that yet.
