Well my take regarding 2.1 patch...I noticed prior to the patch that other colors were more robust like the (green,blues,red and yellow,etc).But skin tones were a bit bronzy.
After 2.1...I noticed skin tones were more natural and blacks deeper "BUT" I feel that the other colors green,blues...etc look a bit washed out and muted.They did not have that vibrancy like prior 2.1.
For instance I watch espn alot and with pre 2.1 the colors used to jump out at me but the host were a bit orangy.After the patch I can tell the colors felt muted and the colors were not popping as prior to the patch but the host looked to have a natural skin color.
I wish this patch gave me both of both worlds, great skin tones with the robust of colors.
