Ken's a good guy-his shop also fitted all of the upholstery for my TE's 3rd seat (had to re-cover a tan seat) and did a beautiful job.

And instead of paying Colortek, have you tried simply applying some shoe polish? I regularly do just that to my driver's seat bolster, as it's always had a couple of wear lines/creases; polish lasts months, costs nada, takes seconds, and moisturizes the leather and will decrease the chances of the "cracks" extending.

Just my 2% of a buck, based on polishing military boots for 10 years and never having one crack through!
