Still trying to demystify the screening process here. ( thank you on previous threads)
I have just got results for 2 airplanes, with the 313 accepted where I was certain of rejection and the b738 rejected where I sure of acceptance.
Another interesting fact, if I may, is the exact opposite screening result at planespotters, where the same 2 exports were screened.

Nevertheless, I would like to try to understand how this hue/color saturation is judged here

I m guessing it is an over saturation, since the hue is unchanged. I do not believe it is an under.

Thank you
