No, it will pass though unchanged but your biggest issue would be the hdmi spec but since your tv on LG's site says it has hdmi 4k 60fps spec ports (does not say its hdmi 2.0 which is confusing) I would say get a HDMI 2.0 receiver in the first place. It looks like what you want your setup to be is a pass through receiver to handle the audio and the video to be handled by the tv.
EDIT: seems your tv supports this:
