AVR receivers will look for the DTS signature in the LSB area of the pcm stream. They will ignore that the bitstream flag of the original S/Pdif stream is "off", if the DTS signature is detected in the pcm stream itself. I guess a version of this is also valid for HDMI even though the pcm frames are sent in chunks.

So it doesn't matter if Kodi supports DTS or not (ie don't turn on the bitstream flag), as long as the sound stream is bitperfect the AVR will probably decode it anyways.
