I have both the HDTV broadcast and BD of Raiders, and I have to say I much prefer the warm tones of the BD...though I'll concede that the digital grading on the BD is pretty glaring, and this certainly is not what the film looked like theatrically. Of course, both are improvements over the horrid DVD.
I never minded either the cobra reflection or jeep "flaws", but then again I never minded the "fixes" either, I think these kind of minor fixes are fine, I'm not THAT much of a purist. I don't mind cleaning up things like matte lines either. I do think it's interesting that Spielberg chose to leave one of the fixes in there but undid the other.
