The T-Mobile software updates page lists the Galaxy S6 and S6 Edge among the devices that will be first to receive Android Marshmallow. In November 2015, a leak of Samsung's plans for the Marshmallow rollout revealed that the Samsung Galaxy S6 has been tested and approved with the new OS, and is scheduled to receive it January.
Samsung opened up beta testing for Marshmallow to UK Galaxy S6 owners in December 2015. The beta build offered users a look at the new TouchWiz interface, along with other Marshmallow features, such as Google Now on Tap, Dose mode and app permissions.
The call for beta testers has now closed, but so long as the beta testing goes well, you can expect the stable build to roll out promptly.

Among the improvements noted by T-Mobile is a fix for the 'camera LED flashlight' issue. Whether this is the same Galaxy S6 camera problem we've encountered previously, we aren't entirely sure, but we're inclined to believe it is. You can expect some improvements to the fingerprint scanner, as well as various bug fixes.
One unexpected addition is RAW support for the camera, as discovered by XDA Developers. The 5.1.1 update also brings lower ISO settings.
