When the histogram looks like a comb after being adjusted then this
is usually indicative of lack of luminance detail in the image.
When this happens (as in your example) the quality of the processed
image will usually be sub par.

IMO if the histogram looks like a comb after being adjusted then
the adjustment was overdone, or the image did not have enough
detail to support the adjustment.

If you are using the image of your (adorable) granddaughter for an
example demonstrating this technique then please forgive my
nitpicking. If this is a real world example of levels adjustments
then I consider the adjustments to be somewhat overdone.

Nice of you to post this, very helpful information.
