TimW:
I read back through this topic of yours and it's a good one. Archie Struther's last post says most about this subject so far, I think.
I believe, and I think Archie said as much, that just because a golfer (even quite an observant one) doesn't really notice a course's greens does not necessarily mean that they are not or cannot be good greens, or even very good or even great ones! And certainly when you qualify the question to the first visit.
This question can have much less to do with greens themselves in certain cases, even many cases, and much more to do with the application and existence of certain basic "art principles" or "sensory realities", if you will! In other words, there is only so much a golfer, or viewer can take in at once, particularly when trying to play golf too.
Many architects are aware of things like rhythm, balance, proportion and particularly what you're asking about "emphasis", when it comes to the "art" of golf architecture!
How much of that any architect truly concentrates on consciously is a good question! It's likely modern architects more than the older ones, since "art" principles and such have probably been applied more on modern golf courses than some of the older ones with things like the subject of "landscape architecture".
Did a man like George Crump concentrate on "art principles" when he spent five years on site at Pine Valley? Or, if he did, how much did he? I, for one, don't know that he did! I have never seen anyone mention that he did with all the documentation of the creation of Pine Valley that I've recently looked through. And as you may know Crump died unexpectedly and the club at that time went through extraordinary efforts to document in detail what they thought Crump was interested in at Pine Valley and what he was trying to do.
But there is a lot going on "visually" at Pine Valley, like many other great courses, and the "emphasis" or the "visual focal points" are many and dramatic and clearly may pull the eye away from other things, like the greens, no matter that they also are world class!
Did a man like Crump mean to do that or even have that happen? I would bet that on both, he did not! He very well may not have even been aware of it or even aware of the subject since it seems he was concentrated on building some of the best holes in the world for strictly the "playability" of them!
But just to make the point visually; if you were to somehow pull away from the greens at Pine Valley, or many other courses with great greens that may not pop out visually, all that competes with them visually, you would likely see them as great greens indeed as they then would become the "emphasis" and visual "focal point", and you would see them for what the really are, sans the extreme visual competition they have!
