And? What algorithm was used for downsampling? What was the high frequency content of the downsampled imagine after doing a psuedo inverse with upsampling? How closely does it match the Samsung output?
My point is that there IS an experiment which would show that Samsung is doing some nonstandard processing likely involving replacement. The evidence provided is insufficient to show that
You have clearly made no attempts to read the original article which has a lot more evidence (or are actively avoiding it), and somehow seem to be defending Samsung voraciously but emptily, so you're not worth arguing with and I'll just leave this here:
I zoomed in on the monitor showing that image and, guess what, again you see slapped on detail, even in the parts I explicitly clipped (made completely 100% white):
You can upscale a 170x170 image yourself, if you're not familiar with what that looks like. The only high frequency details you have after upscaling are artifacts. This thing pulled real details out of nowhere.
