Sorry, I somehow skipped over your post. I'll blame it on posting from my iPad.

Unfortunately, this is a terrible answer, but it's difficult to describe, and I know it when I see it, but Plasmas do not exhibit the look I am talking about.
What I'm probably describing is the way that brighter lines are subtly thicker than dimmer ones, are not confined to hard pixel boundaries, and the gaussian beam of a CRT.
This is not the best comparison, because that's not what the intention of these photos was, but this is probably the best explanation I can give.
Single "pixel" spot on a CRT:
As brightness changes, the spot will increase or decrease in size.
Horizontal line on a CRT:
Horizontal lines on an LCD:
Note how hard the edges are on the LCD, and how the subpixels are uniformly lit. While I don't have access to a Plasma do do the same comparison, a PDP up close like that, looks the same as an LCD—uniformly lit, hard-edged subpixels.
A shadow-mask CRT would have more squared off edges than the aperture grille one photographed here, but still exhibits that "glow" that does not exist on flat panels.

The only one of merit to me is the cross-talk (blooming + dynamic MLL). Both are fundamental to the device.
Stick to the OP question. With regards the OP question CRT and PDP are very much comparable with regards to reflection from internal surfaces. LCD with color filters and a polarizer is absolutely not.
PDP weighted subfields produce a 60Hz duty cycle flicker that is nearly identical to CRT in presentation.
I find that flicker is far more pronounced on PDP than it ever was on CRT, and when I look at a CRT, it's the dynamic range they offer, the lack of artefacts and smoothness of the image that I notice much more than anything else. A local-dimming full array LED backlit LCD recreates this far better than anything we have available today in my opinion.
I never watched my CRTs at an angle, just like I don't try to watch my LCD at an angle, nor did I try to use them in brightly lit rooms, so neither of those are key to the CRT look for me, the image
is what's important to that look for me, not the display panel.
on an LCD is far more like a CRT due to the excellent gradation, lack of dither and other artefacts, smaller pixel pitch, the flicker from a scanning backlight is more like high refresh rate CRTs (60Hz flicker is not a desirable trait if it can be avoided while still maintaining low persistence) and lack of jarring motion artefacts.

Can't be done. It's my understanding that Plasmas are not built with power supplies capable of handling the amount of current this would require. (Xrox will likely be able to give you a better answer)
