In 4K screens and above, these old files have to be stretched to cover the whole screen. This does not result noticeable loss in quality?
Not really. I have a 5k iMac, so in 1:1, the files of my R-D1 only cover a part of the screen. But since the pixels are too small to be seen individually anyway and also since the scaling algorithms used by modern software are pretty good, you won't notice any obvious degration.
Of course, if you are a pixel-peeper... then you will see it. But then you wouldn't buy a R-D1 in the first place. The camera still produces very pleasing images with great and smooth colors.
