i believe that this is actually how the deleted scenes will look on the blu ray. based on this:
REDACTED
i just want to say that this is not my contribution, i found it on reddit. if this is breaking a rule i will remove it.

but it looks like it is just gonna be a time code in the top left, which i don’t believe will be that hard to remove. it is a box. all you have to do is screen-shot some frames before and after, put them together in photoshop/gimp and keyframe them into the video via after effects. that is a lot easier to do with the burned in time code than it is with the box watermarks.
