comment Is there a lossless sRGB to CMYK conversion?
Any half colors are added only to reduce visible dots in very light colors. Those do not expand the gamut at all. However, addition of inks that add extra primaries (such as bright red or bright green) may expand the gamut because there's a limit on how saturated the ink can be.

comment Are RGB numeric values equal to CMYK percentages?
With high quality inks, mixing all CMY inks together will not yield to dirty dark color but black or really dark grey. However, the black ink is used instead because of thing called ink limit. That is, any paper has a limit of how much ink it can take for any given area. For example, say it can take 1 ml per square centimeter or the ink will flood or spill over the paper. Using 1 ml of black ink gets darker black than using combination of C,M and Y totaling 1 ml of ink. As a result, K is added to dark colors to increase contrast. However, using CMY over K would result in more neutral black.

comment Why do JPEGs only look right when exported from Lightroom in sRGB color space?
The sRGB color space is designed to match an average phosphor covered electron cathode ray tube display using display gamma close to 2.2. Most non-wide gamut displays try to emulate that color space because that is de facto color space for all software that is not color management aware. A good operating system would apply automatic from sRGB to display profile color conversion during window rendering unless a piece of software has declared to be color management aware. Unfortunately, no common OS does that. The closest match is Linux + Compiz 0.8.x + CompIcc plugin.

If your monitor is "affecting the image" after it has been calibrated and you're using color management aware applications or OS that defaults to correct color space for unmanaged applications, it's time to get a working monitor. Yes, that means throw or sell that TN panel right now. Get a nice VA or IPS panel (preferably the latter) and calibrate it with real tools (that is, use spectrometer instead of colorimeter) and your monitor will not be "affecting the image" anymore.
