Wow. Would those include any commentary on power supply capacitors that lead to warmup problems or general color quality degradation on this unit over time??
The only color degradation issues I can speak to would be changes in the TV's white balance due to uneven wear/aging of the phosphors, which could be corrected via the TV's grayscale controls (RGB "drives" and "cuts") in the service mode.
The XBR800s also have an anti-glare filter that's bonded to the screen with a rubber cement-like adhesive, which may also yellow over time. I never liked the filter though, so I removed it. And you can get an idea of the difference in color with and without the filter (and the adhesive that bonds it to the screen) here...

The filter itself had a slightly greenish cast, similar to polarized sunglass lenses.
I consigned my 34XBR800 to the recycling heap not too long ago, but never had any issues with the capacitors or power-ups, in the 12+ years that I used it. I was pretty gentle with the TV though. And used it mainly at night in a dimly lit room for watching movies (with the Contrast settings configured quite low in the service mode). So there wasn't much "wear and tear" on the TV. The picture probably looked better on the TV when I got rid of it than when I bought it new, because I spent quite a bit of time tweaking all the color, geometry, convergence, etc. controls in the service menu to get it looking as good as possible for my own viewing.
Posting some pictures of your issues in one of the capacitor-related threads for this TV might help to jog someone else's memories re some of the problems you're having. I think alot of folks finally gave up on their XBRs though, and either went plasma, or LCD/LED.
Newer "VA" and "FALD" LEDs have greatly improved contrast and blacks over conventional fluorescent backlit LCDs, esp. at optimum viewing angles. And the late model Samsung and Panasonic plasmas both produced very CRT-like images to my eyes, with very respectable (though not quite CRT-like) blacks. I tried "open-box" examples of both in my home before they all disappeared, and liked them pretty well. The main reason I decided not
to get a plasma was burn-in. For folks on a budget though, the 1080p Samsung 51F5300(B), and 720p 43F4500, and Panasonic 50S60 and 42S60 (both 1080p) all produced very nice CRT-like pictures, with great angle of view*.
The new 2015 Samsung JS8500 4K LEDs also look pretty good to me in stores. But they ain't cheap! And are only 120Hz, despite their 240 "motion rating". (Higher refresh rates of 240Hz and above produce better-looking motion on LEDs imo.)
(*A shortcoming on many VA LEDs.)
