The image stabilization and a proper optics set seem nice, but honestly 41MP sensor is practically useless itself. Even professional cameras with high quality sensors are not usually sensor resolution limited - i.e. increasing resolution wouldn't be much use since at the pixel level the image is already at a significant noise level/optics limited. For such a small sensor and f-number, I guess 41MP is not only useless, it's detrimental, because you're paying for nothing. Although it's possible it may improve quality a bit wrt lower resolutions due to downscale averaging.
... and by white paper you mean "marketing material"? I had Nokia PureView 808 and I agree that it is nice and helps making good photos when downscaled. Idea to use sensor in this way is really interesting but in the end that just covers one little thing from many that are important in photography. For the same (if not lower) price you can buy good compact (if it must be pocketable) or system photo camera (if size matters but can be slightly bigger) and enjoy all benefits of photography like high ISO numbers, big sensor (not in megapixels but by area that is more important than megapixels), possibility to change aperture (this one is big for me because of bokeh) and some other.
It is just a little bit bigger sensor in the end with one smart idea that is not contributing much.
