Basically, no.

The FSEQ/ESEQ is just channel data. What pixels are on at what time.

The $SONG notation is used by xLights to create the exact text when you render the sequence, it's not actually stored anywhere, much like the effects (butterfly, single line, etc) are not known outside of xLights
The show player has no visibility on any of this data.

If you put $SONG variable and reneder the ESEQ, if it can figure it out, it'll render the name of the Effect Sequence instead, or it'll remain verbatim as $SONG. I'm not 100% sure exactly what'll get subsitituted, likely the name of the source sequence file.
