As far as I can tell yes. I tried the usual test files first, where there is a FEL stream from another movie present, I also tried the FEL TEST ST DL P7.mp4 with the "Dolby FEL support" text encoded into the EL. The EL layer is decoded AND displayed.
I'll try watching Saving Private Ryan today - IIRC this showed anomalies when EL layer is discarded.
