A column could hide that angle in that case...
I wouldn't put a column so close to the screen wall, but if I did, I would be very selective about it's finishes if up there.
I myself like the idea of hiding the entry door up front, as part of a shadow-box front area, to preserve the dynamic range of a projector. The JB demo room is actually a high performance cutting edge ATMOS room. It's a little simplistic in it's fabric panel walls, and some blackened door hardware would be another thing I would change.
There is a lot of variety of home theater styles beyond the column/wainscot/soffits theme, but the internet seems to bombard us with those. Much of what I would do, and where the entry would be, would be based on the style of the room and also be about the layout of the room before the theater.
It is a great space, with but a minor intrusion. It kind of comes down where the money is best spent and the desired looks.
