Joe Kane is one of those who mentioned this issue in a recent AVS podcast. The problem is not with downscaling, it is with downscaling to a very similar resolution, as it becomes very difficult to avoid artifacts. Much less of a problem if you downscale to a significantly different resolution, like from 4K to 1080p.
I'm quite sure that most movies transferred to 1080p from a 2K master are cropped, or you would have similar issues. As it's only around 5% (2.5% on each side), I don't think anyone has noticed or would complain. There would be artifacts too (and there are in many blurays) if downscaled from 2K to 1080p.
I don't have any evidence, but hopefully someone more knowledgeable will provide some or prove I'm talking through my posterior orifice
. I just hope they will go on cropping 5% instead of downscaling as I'd rather have a slightly narrower picture with a 1:1 ratio to the master than a downscaled picture to fit a 5% smaller resolution.
Honestly, as long as they crop and don't downscale I couldn't give a monkey. It's very unlikely we'll ever get 4K or DCI for consumer content, so it's mostly irrelevant anyway.
