.BRAW imported into Adobe Media Encoder are decoded by default with the "Camera Metadata" setting, like on DaVinci Resolve. This means that it will try to read the .sidecar next to your .braw to apply the color grade. If it can't find it, it will use the settings from your Camera when you shot the footage. If you changed the .sidecar after importing the footage, it will keep the same old .sidecar values until your restart Media Encoder / Premiere Pro.
