Your logs show that you are playing DTS HD-MA 7.1. PMS cannot transcode 7.1 channel of DTS, only the core DTS 5.1 portion, so the best you can get is 5.1 channels. Your TV reports it supports 5.1 channels for AAC, AC3, and EAC3. For 5.1 channels, there is no noticeable quality using any of these codecs so
PMS has chosen AAC.
Your logs also show you playing a DD+ Atmos 7.1 track. PMS can transcode all 7.1 channels of this so you get EAC3 7.1.
PMS is converting appropriately. If you prefer 5.1 EAC3 over 5.1 AAC, there is no way to force that, but as mentioned before, there should be no noticeable difference.
