Wouldn't any post exposure adjustment cause loss of some color information? So when you 'boost' a color you are 'stretching' it and the software needs to interpolate and fill in the gaps so then there would be a chance of color banding. Right?

Posterization only occurs if software uses poor precision or works in an imprecise bit-depth, like 8-bit, on relatively noise-less areas of an image. You should not get any posterization in 16-bit editing.
