You're going to do much better playing it from a disk than you will EVER do from streaming. Just FYI.

That statement is very wrong. Here are the facts with sources.

A true 4K film could NEVER fit on a disk. So no that statement is SO far off I have no idea where you even got it. You cannot fit TRUE 4k ON A DISK. It's too big!

Just reporting facts:

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.


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.
