Theodore, the good news is that all of the edits/tweaks that you did
(1) can be saved as a preset and/or per-camera default. This means that you can easily apply the same settings to other images. And future images can automatically use these same settings, if you find that you like those results, and
(2) can be undone / discarded with no harm done, so if you decide tomorrow that you actually didn't like those results, you can simply change the settings or toss them away.
To address some of the other questions brought up in this thread: digital camera systems have spectral sensitivities determined by the lens and color filters; they are generally sensitive to the entire human-visible spectrum and so they see everything we see. However, these sensitivities aren't colorimetric and hence recorded colors cannot be transformed into a standard color space without some distortion (e.g., some recordable colors may be mapped to colors outside the target gamut, and the target gamut may also contain some non-recordable colors).
