People also fail to realize SONY is not true 4K if it fits on a blu ray all it is is enhanced. It's still 1080p. HUGE difference. And those are the films they are putting on their player. Otherwise a 2TB hard drive would be filled up with less than 10 movies.

Sony, though, believes it has something with which to fill the current 4K void. A sort of 4K–assisted Blu-ray, for want of a better description, dubbed ‘Mastered in 4K’.

The idea is that the Full HD film versions on Mastered in 4K Blu-rays have been derived either from more-than-4K masters of their original celluloid prints or, in one or two cases, downscaled from original 4K digital footage.

To be clear, the final digital films on the Blu-rays still only have the same 1920 x 1080 pixels of actual resolution as normal Blu-rays. But the argument goes that because these full HD files were derived from higher-resolution masters, their images will be more precise, with better colours, less noise, and enhanced sharpness and detail. Not least because the higher-resolution mastering process will provide more detail from the original print for the Blu-ray masterers to draw on when going through their (hopefully…) frame-by-frame compression process.
