A visit to Seminole will provide an incredible education.
The shape and slope/contour of the greens, along with their unique relationship with adjacent bunkers and slopes is incredible.
Some of the greens, like # 6 are worthy of days of study.
Pat, unfortunately when you post many of these sort of comments/questions without photos, it probably only invites responses from a very few people. Isn't Seminole a rather difficult course to get an invite to play? I'd be interested to know how many folk can actually relate to your question and comment, and actually have played there, let alone spend days studying a green complex, as you query.
Perhaps one has a far greater opportunity and ability to experience spectacular greens/surrounds at St Andrews TOC, or Wild Horse.
Unfortunately, the course write up here on GCA also has a scarce 4 very low quality photos.
I lifted this one from one of Whitten's list of top 100. A quick search didn't yield any more photos to give some illustration of what you mean.
Going by the photo, it appears to me that the 6th may have some qualities similar to 10th at Riviera. It appears narrow and somewhat hourglassed and slightly less angled approach, but with dangerous bunkering front and back. The apparent cut of the collar would atleast seem to give the backstop of the sandblast rolling from a crown or slope on the green to atleast have a chance to hang-up in the rough cut next to the bunkers. Now, if it were mowed with putting height of cut right into the bowels of the bunker edging into the green, that would be positively AUZZIELIKE.
