May I give my 2 cents about how I sort the things out of this SAR/DAR complexity when I encode in FTAB (for my LG UHD TV) ?
After the 3D encoding, I use MKVToolNix with the header editor, and edit the "Video display width/height" of the video stream with the target 1920/1080 values (usually they are set to same values as "Video pixel width/height" of 1920/2160).
Maybe I could set the parameters right in BD3D2MK3D that would do it for me without tweaking, but I don't remember ever succeeding with this, and this header tweaking gives me a 100% assurance that everything will play fine on the TV.

Some TVs require to set the aspect ratio of the combined view, and others require the aspect ratio of the final display (16:9), and some (like my Samsung) ignore totally the AR settings and disp[lay the movie in 16:9 full-screen anyway (and this is not a bad idea, because the SBS/TAB standard REQUIRES a 16:9 movie, with the black bars if necessary, so displaying it in 16:9 anyway makes sense.)
For a good result, you may have to change the AR settings with the menu Settings -> Full SBS/T&B aspect ratio. Note that there are two AR: the DAR set in the MKV header and the SAR in the video stream, so there is a total of 4 combinations. I suggest to encode a little clip several times just to verify what setting works for your TV. You can already exclude the default settings. :-(
Note also that there is no problem in Half-SBS/TAB.
