Not sure what FHD is?
FHD Full HD (1080p)
UHD Ultra HD (4K)
I was asking about the the 2020 FHD blu-rays that came out with the 4k ones. But I guess since those come from the same “new” sources as the 4K versions, the colors, the tighter framing etc. are identical to those of the 4k ones. Minus the higher resolution and HDR ofc.
Keep in mind those are only available in the box with the 4K, the individual releases are still the 2011 version.
