[uae] Palette differences between real amiga and (Win)UAE

Hi! I took a screenshots of Monkey Island with native grab tools and i
compare it with screenshots made with UAE 0.8.28-r2 (external tool) and
WinUAE 1.0 (internal tool). Wow! Colors are differents in all the three
grabs!

Some examples (RGB Values):

Colors          Real Amiga              WinUAE          UAE
-------------------------------------------------------------------------
White           (255,255,255)           (240,240,240)   (240,240,240)
Yellow          (255,255,84)            (240,240,80)    (240,240,79)
(light) Red     (255,84,84)             (240,80,80)     (240,79,79)
Dark Blue       (0,0,169)               (0,0,160)       (0,0,159)
Violet          (169,0,169)             (160,0,160)     (159,0,159)

Does (Win)UAE aim for perfect colors? Is this beavior fixable?
Here the links of the grabs, including a raw iff (ilbm) one taken directly with amiga (i converted this in png).
