In those cases, it boils down to 5.1, 7.1 vs Atmos. Sometimes the HDR is more subdued, but the picture quality is still 'good', it's just that the 1080p version was already excellent to begin with. Sometimes though, it's hard for me to spot too many differences between the 1080p Blu-ray version visually when those versions already have some of the best transfers. That's because it has to display programs in the standard HD format, the 4K ultra-HD format and the 4K HDR (high dynamic range) format. The Last Jedi (say what you will about the movie itself, but the UHD looks and sounds great) Your 4K TV is really three TVs in one, Soneira noted. They can simply look 'pretty good' if the audio is amazing and vice versa. They either have to look really good, have phenomenal audio, or both. For those who want to self calibrate their UHD HDR television rather than spending hundreds for an ISF or Calman Home calibration, the Spears & Munsil UHD HDR Benchmark (UHD Blu-ray Disc) is now available on Amazon for 40. I tend to go after films that don't just look good though.

If you have the time and patience to use the disc yourself, you will (imho) get a picture which is fabulous.

A more expensive tv 4K/OLED would be worth doing.

The Matrix was really well done, as was The Matrix Reloaded, despite the second film being more of a collection of cool scenes than a really good film. Actual ISF calibration would be better without a doubt, but as also 10x the price minimum, it wasn’t worth paying half the cost of the tv to calibrate. In terms of other movies just for the picture quality and HDR though?
