And let me be clear. If you can figure out what something is meant to look like in reality approximately without any Warts.
When you compare it to several versions with Warts you can understand how each of your sources is altering or differing from what it looked like in reality approximately. And how much say a certain source is altering what it would look like in reality.
you can then infer a difference of how much each of your references is off by to come to a mean average.
So I was trying to be helpful in a lateral way but you simply have not grasped that.
Nevermind & Good Luck
I very much appreciate any input or suggestions, so if I misread your post I apologize, but you should also appreciate, that you may invite such responses by continually taking a condescending attitude, by using terms like “you are very much ignoring”, “are getting a bit confused”, “you are not taking in to account”. These are all assumptions on your side, but you state them as fact. I’m very well aware, that different sources can give different information, and I’m also aware that the neutral "real "colors can be helpful as well. I created an entire thread on the subject, and built a software tool specifically for this purpose. I’m however also aware (thanks to poita), that film makers often alter the look of scenes during grading. Sometimes these alterations can be subtle, such as a slightly warmer or cooler tone, but sometimes these alterations can be more radical.
Incidentally, I agree the R2-D2 frame has a blue cast, which is a bit obscured by the lower contrast and yellow/green tone of the video.
