One reason might be that many of them have very narrow differences in value between grades, so there’s not not much incentive to resubmit them. As a result, a good number of conservatively graded examples have remained in their original holders.
Over the years, I have noted that when a series is out of favor that the TPGs tend to get more conservative with the grading. Conversely, when a series is hot, I've seen them get more lax with the grading.
The "old commemorative" coin market has been weak for years. Perhaps the tighter grading standards have left more openings for the gold CAC sticker.

Gold sticker also indicates a third party misstep. An incident of grade deflation if you will. Certainly a good thing for the submitter.
Tons of uncrculated commems out there ....better chance of getting stickers

Completely agreed with MarkFeld, but I'll add that the price structure of the commem market also limits the amount of coin doctoring in the series.
