I wouldnt know honestly since im currently using an app to dim and darken my screen brightness. But hey you must have really good eyes then.
I think Dongho's complexion also helped me spot it tbh... His pale skin is highlighted with his hair
I slightly notice the darker brown hair change of Dongho..
Like the shade of brown is almost close to very dark chocolate or roasted brown..
There is a panel that shows his hair to be so dark that it is close to black..
Ps: I am not a color expert.. So my description might be wrong
