Honestly, it seems like most, if not all, of their videos shot exclusively for their YouTube channel has this problem. I'm sure it's a combination of things, such as camera settings and not bothering to do any color-correcting in post, but it would be nice if they could fix that. I mean heck, my little commercial Handycam has a setting that helps improve the color to where it doesn't need fixing in post, but if that's not the case, simply adjusts to the brightness, contrast, and saturation would be very beneficial - if done as an adjustment layer, it could be applied to the entire video, and they wouldn't have to do it clip by clip.
