No, there is no chance.
eARC requires a specific HDMI chip that can support using the Ethernet channel for audio duties. There is no signal coming from LG that their HDMI implementation goes beyond standard HDMI.
If LG had any plan of offering eARC for 2018 models, be sure that we knew about that.
We can expect
that eARC will be implemented in 2019 models and maybe
full HDMI 2.1 in 2020 models (mostly 8K models, where it really counts).
Let's not forget that eARC is useful in limited scenarios:
1. Streaming originated in the TV apps
2. Soundbars (very few HDMI ports, maybe just 1)
Since no streaming service is using lossless audio, you do not lose anything.
If you think that in the future there will be lossless audio streaming, the streaming service will always downgrade the audio to what's compatible with the destination device, so you will get Atmos by DD+, instead of TrueHD.
When the lossless streaming will become pervasive (2-5 years, maybe) you can upgrade the TV or you can use an external media player / streamer.
Right now there is no reason to bother with the eARC for futureproofing your TV.
HDMI protocols change every 3-4 years, so your "futureproofed" TV will be "obsolete" already...
Moral of the story: Just enjoy your current setup!
