I think the best way to raise your ISO 200 5 stops is first to do it in the raw file, and not use 3rd party software? I would have taken the ISO 200 through DPP and pulled the slider up 3. Beyond that, you have to use levels or brightness sliders to go the extra 2 I believe. I am curious how others would raise an image 5 stops personally, but the best way is from the raw itself, and not from the JPG.
I would just do it in the Adobe RAW converter, either ACR, or in LR. Either way that offers +-5EV on the exposure slider. The other advantage of using the Adobe converter is that it offers sliders across several other ranges of luminance. You have Highlights and Shadows, as well as White and Black point sliders in the basic panel of the RAW converter when using Process Version 2012.
Here is a quick example, but not from an 80D, but my lowly 50D. I shot the first shot at ISO 3200, the maximum non expanded setting of the camera. I shot it in Av mode, with no EC, then used those exposure values in manual for an ISO 100 shot, which is 5 stops difference. I then processed in LR, using the following settings:
WB; Tungsten
Clarity +25, Vibrance +20.
Sharpening Amount 75, Radius 1.0, Detail 0, Masking 100.
Zero Luminance NR
Chromatic NR Amount 25, Detail 50, Smoothness 50. The NR settings are the Adobe original defaults.
I also had Remove Chromatic Aberration selected. This is the ISO 3200 result.
Plus I had output sharpening set to Screen/Standard.
