it will improve colour depth

My friend in almost any photo editor we have saturation slider which is not just 0 and 100%. So you could have low middle and high saturation or anything in between.
Also you could have not enough or too much.
In addition in basic electronics we have saturation currents and so on. Whatever.

About shooting with cap on - I can clearly see noise when my cap is on! This means this is not shot noise, because there is no light entering. So you can just shoot at different ISO levels and see if this is good for you because it will be added to the image with or without shot noise. So this images in addition to shooting solid gray will give you enough idea what is noise and how much it is.
On topics about analogue and digital amplification, types of noise, measuring, science and so on I just do not have time and willingness to continue this pointless debate. Result from this is zero just from the start.
