Question regarding available backlight modes

I have one Philips TV with ambilight and I want to get the 3 HDMI 2.1 Sync box for my main TV. Philips has a mode where the background is lighted with medium white color plus it adds colors based on image when needed on top of that white - overall it seems it has less eye strain this way. Is there a way to have something similar set with Fancyleds? - on the reviews I've seen only folks projecting exact color from the tv.
