How to decrease the gradient banding on SR MBP's

-

(this cross-post between mentioned on thread. however, i'm reposting seperately others can see easier , benefit it.)

figured out how around gradient issue having. appears booting standard color lcd profile (or profile created colorsync) caused distinct banding when looking @ color gradient image attached. however, if switched srgb profile or color profile downloaded off forums (i assume not created using colorsync), restarted mbp, , looked @ same color gradient banding less apparent. tested on friends sr mbp , got same results. once restarted can switch standard color lcd profile , gradient still good. however, you're square 1 if restart (or think if load lcdtest2 or 1 of apps) profile. makes me think color banding people see not result of 6-bit screen other issue actual color profile aswell.

doesn't rid of yellowish hue might have toward bottom of screen (the reason why i'm taking mbp back), should make gradients better.

let me know how works.
