Halo 2 Classic's Default Gamma Seems Off

Is it just me?

To my eyes Halo 2 looks slightly washed out, it seems like the gamma setting should really be somewhere between 5.7-5.8 instead of the default 6.0.
When compared to other titles at default settings it definitely seems to have a “grayness” that usually implies that gamma is too bright in my experience.

Halo CE Classic seems pretty much bang on in comparison although setting that particular title to 5.9 smooths out the shading in dark areas better.
