Atmos and DTS-X is like putting cream onto a baked apple pie. The movies are now being mixed at the post-production using objects and encoded in ATMOS and/or DTS-X so that modern cinema's have something better to offer the movie goer. Think, they are loosing customers to Netfix and people just not going out to the movies.

Your 5.1 is about 88% as good as a home ATMOS / DTS-X
Your 7.1 is about 93%

So Atmos and DTS-X does add something, but it is not an revolutionary that much better experience. The average home theater is not perfect and unless you are throwing hours and thousands towards getting to that next level, you are not going to find it that much better.

I watch movies at home to escape for a bit and enjoy the entertainment.
