Saw this was noted on Twitter, so:

For anyone who is finding their character a bit washed out, the "gamma correction" setting might be having an effect. It is currently set to 50 as the default, but you can change it as you see fit.

I changed the gamma correction to 30 to see the difference, and while it's not super noticeable all the time, it does seem to have a difference! The lower correction level seemed to fix most of my issues with the vibrancy.

At least to my eyes the color looks more vibrant. Wanted to pass along the info for anyone who found the colors to be off so that maybe you could have your worries put at ease.
