I just receive my 437 yesterday. I watched it from noon till 11pm. I think I may have seen a rainbow or two but not while actually watching the set. I was looking at the manual and I may have seen the effect out of the side of my eye. Never while actually viewing. I had no eye strain.

it seems most people catch the rainbow effect when looking away from the TV and then back at it, kinda like what happens when doing one of those magic eye pictures. It seems like you can catch a rainbow when your eyes are not properly focusing on the picture, although I imagine subtle black lighting would fix that too 
I can see rainbows primarily when there is a small portion of the screen with a light image and the rest mostly dark. If I look away and then back, or dart my eyes back and forth, the 'rainbow effect' clearly visible. It doesn't really bother me, though, and is almost never apparent during 'regular' viewing.
If you haven't seen rainbows on this set, and don't want to, stop reading now...
**Disclaimer: Don't blame me if you read on and watch the scene I point out, and don't like the results***
I'm evaluating this set, and tonight I watched Attack of the Clones. About midway through the movie I started seeing the rainbow effect (never saw it before, but knew immediately what it was), and near the end of the movie there was a scene that showed the effect despite my best efforts not to see it.
Scene 47, after the Count gets off his ship and meets Darth Sidious, there is a scene where he and Sidious start walking together (Sidious says 'You have done well'). There is a light source behind the head of the Count. If you don't see a separation of colors looking from the Count to Sidious, be happy. In this mostly dark scene, my eyes naturally follow the conversation from man to man and the light source in the scene amplifies the effect.
To me, the distracting part isn't the actual sight of the color separation, it's the second after where my brain says 'wtf was that'. Perhaps this goes away with time.

That's exactly what my brain said, too!
And, it describes the "rainbows" experience very well, IMHO.

Have the service and user menu tweaks been applied to the set yet? I found the rainbows to be much less obvious on my tweaked machine than on the same model which had not been tweaked using the same source for both.

No rainbows (even on SWII dvd last night). No eye fatigue. About 75 hours on my 437w (dvd and analog cable). Family of 4 non-videophile viewers. Had a friend over recently who frequently suffers from migraines. She experienced no problems after about 2 hours of dvd watching. I've employed all SM tweaks except color adjustments. Love the set more each day.

Had 437W for about 6 weeks. No rainbows, though I am admitted novice in detecting them. Definitely no eye fatigue. DVD on component input, TV is straight cable.

If you do a search for HRPULL on this forum you'll find my rainbow experience.
Rainbows are real for some people. My wife and I are statistically odd since we both saw them all the time. One article reference on this forum stated that with the new technology color wheels only 1% or so of the population should be bothered. Having read this before buying the 507 I wasn't concerned. I guess I must be neurotic or something since I took the set back after 4 weeks of trying to live with them. My wife saw the rainbow before I told her about it - so I don't think I taught here to see them. She asked me about the flash and I explained the rainbow effect. The problem got worse over time for both of us.
