Why is videos on Plex so dark?

Whenever I’m streaming Plex on browser and my Roku the moves are a lot darker then if I stream using VLC or any DLNA device.

It doesn’t matter if I stream from my Plex server or a friends server it’s the same results. I can also replicate this on my Macbook pro, Window 10 desktop, and my Roku. I’ve been unable to find a setting on Plex that fixes this issue. Is there a setting I’m missing that fixes this?

Here is an example taken from plex streaming on Chrome vs the same file streaming via VLC. No video setting have been changed on VLC.

VLC on the left ----- Plex on the Right streaming with Google Chrome.
