My TV is an LG too. But other UHD HDR films i have don’t seem to suffer with being overly dark and dull like the Star Was films. Even on Disney+ the HDR on films other than SW seem fine. Netflix HDR is fine too
The Blu-Rays look great though. Colourful and not dark.
That’s great news regarding the Blu-rays, assuming the “Blu-ray only” set has exactly the same Blu-ray discs as the full UHD set.
Given the problems with the bonus discs, I might wait a bit longer to see if Disney fix them in the next few months.
