No.

Height channels with Dolby Surround Upmixer and it doesn't break the stereo presentation like the past expander codecs.

I have tried both the EX Surround Codecs on older AVRs I had. Pretty bad.

Might be why a lot of people hold out thinking ATMOS isn't worth it. It is big time especially for applying Dolby Surround to legacy content. Hard to believe it came out in 2014 already.
