I read that you can't have enough bass trapping,I see a lot of rooms with the corners filled.
Then I see the ceiling wall corners with only a few spaced out,perhaps 2-3  along the c/w corners.
If  we can't have enough,why don't I see bass trapping butted up beside each other .,filling up the C/W corners.
Some of these excellent looking rooms and obviously some can afford to do what ever they want.
I wonder if I'm missing something.

You're not missing anything. It's just that it's more difficult to hang traps in wall-ceiling corners, and expensive to treat every linear inch of corner surface. But don't forget the wall-floor corners. Those are viable too.

One just has to be aware that sometimes, treating one thing can cause another problem. Well, not really, but sometimes you have 2 'problems' that tend to cancel each other out. When you address one, the other now is not cancelled and shows up.  I've noticed this more in some wall/ceiling junctions than in typical wall/wall junctions.

Not saying it's not potentially a good thing to do, just something to be aware of.

Also, corners are not a be-all, end-all solution for bass control.  There are many other places in the room where bass control can be very useful (reflections for boundary related phase issues, rear wall to address cancellations, front wall for phase related issues, etc.)  Bass builds up by a boundary.  Corners just happen to be efficient since they're the end of 2 or 3 boundaries.  They also offer the ability to get some space behind them by straddling whereas spacing panels multiple inches off the wall can be troublesome and look kind of funky too.

Lastly, (and Ethan and I have had this conversation and agree to disagree) you absolutely can have too much of any sort of absorption in the room whether it be broadband or targeted bass response.  Yes - it's harder to do in the lower frequencies but it can be done. There is a desirable target range for the decay time in any given volume of space for a certain use (2 channel, multi-channel, classroom, etc.)  It's not just a one sided limit where you have to get it down to a certain point.  It's a range that is desirable to adhere to.

THX Ethan,I know about the installation troubles.
As  I had the Tritraps for my corners(2Xstacked)+I had a few left over.
I mounted more tri's on the C/W corners BTB,and then filled the rest of the C/W corners,Looks good sounds good.
Ethan concerning the Realtraps diffusers(I aquired three from James).
You mentioned that they are like icing on the cake,I agree except that the candles are lit also .
I have had them for about three days and no matter what I play it is almost a 3D effect sound wise.
Really it seems like mid and highs have left the speaker boxes  at the cross roads most of the time.
Then there is something on the topend that is really nice on the ears,hard to describe,but I really do like what I'm hearing.Definitely more stage depth and space on the stage,very addictive as it seems the instruments have alot more of their own space on the stage.Should have diffused the backwall sooner .

Hi Bryan,perhaps now it's time for me to look at measuring,to really see what's going on.
So far I've been just going by picts(good thing there in colour ),and doing basic bass trapping first reflections on
sidewalls and ceiling and now BW diffusion.
Figure that those would be a foundation of sorts,course maybe my foundation is to big for the house so to speak.
Measurements here we come.

I was at a dealer's and the room was dead ... lifeless ... I took a non-audiophile friend for an exposure and he was under-whelmed ...

Even the dealer mentioned that the room is over damped / more dead than alive ...

He had very thick wall to wall carpet in addition to generous use of panels ...

Bass trapping is not damping.

Bass trapping is not damping.

That's exactly what I'd have said if you didn't beat me to it. The range below 200 or 300 Hz is totally different from the range above. In normal home-sized rooms, untamed reflections cause narrow ringing peaks, and deep nulls. Neither of these are ever good. So then it's a matter of how bad a low end you're willing to accept.
