g-force, it's a good cause, but unless you plan on documenting each shot individually, you won't be presenting an accurate accounting. There is not a universal "thing" plaguing the Blu-Ray, by any stretch. That many scenes appear to share certain qualities is coincidence, and even within that coincidence, vary wildly.
Most of what you're seeing with the Blu-Ray can be categorized by four classes: 1) Exposure issues, 2) Damaged element recovery, 3) Deliberate color grading, and 4) Lowry.
The exposure stuff I've explained before, in regards to the density of negative/film, and an improper handling of the gamma on the other side of an otherwise good scan. As for #2, many elements had entire ranges of their color degraded, and you can spot instantly which color/elements were attempted to have things put back for. The green lightsaber scene is a classic example. In that sequence, watch the control panel in the foreground's colors, and notice when they suddenly change their entire nature. Ditto a single shot in the sandcrawler over R2's shoulder where his green light panel suddenly shifts cyan. That's element damage, where the film had gone green, and wasn't corrected for properly. There's a ton of that, in various incarnations, all over the film. You can learn to "feel" when the source had whole colors missing from it - the shots get a sort of sepia undertone to them. Many Falcon cockpit over-the-shoulder shots suffer from this, where suddenly everything is sort of brown-ish, but other shots are fine. This is how lobster-men came about. That's a compensation for damage in the elements; an attempt to correct one thing which has consequences elsewhere which nobody was watching or had time to correct for.
#3) is a huge category encompassing things like R2's ridiculously over-saturated blue; an attempt to match his appearance in later films, after which he was repainted using an entirely different process. So simply saturating his blue doesn't work, makes the frame look cartoony, and weirds out other things in the frame.
4) Lowry's process was immature compared to that work today. LOTS of artifacts as a result. Watch the Tatooine sand for 3 seconds and you'll see that with every successive frame it turns green, red, blue, yellow, etc. Convert to LAB or YUV to really get a sense for color instability throughout the film as a result of that process. It isn't on the negative that way, and it isn't on prints that way. For an especially rough example, take the "go that way, you'll be malfunctioning in a day or two..." long shot of the two droids and keep an eye on R2's body. Watch it pop and bounce in luminance and color. For a real treat, examine the three channels on that shot separately and look how utterly fucked up the blue channel is.
Again, you will not find anything approaching a global set of adjustments which "explain" the blu-ray. Like You_Too, you may find a setting which really helps, a lot of the time. Your best bet in this is in regard to luminance. You can globally correct luminance moreso than any other trait in the image. But having restored this film from the 2004 DVD once, I can tell you that it ain't that simple. Every scene has its own "thing." I still wake up in the dark to the awful shifting tides of Tunisian sand dunes.
