Basically you are in a study which calculated for you what people ought to be able to see and you insisted on redoing the calculation yourself incorrectly. The study says people factually can distinguish up to 94 pixels per degree. a 70" screen at a meter away is 24 PPD. You yourself could have easily eye balled 2 screens and come to the correct conclusion but are instead asserting nonsense.
Did you notice that FHD tvs larger than 40" literally don't exist in stores? If people literally couldn't see more than 24 PPD than at the more typical 10 feet viewing distance a 70" screen at 640x480 would be just as good as a 70" 1080p was at a meter away! For a 50" you could go down to 320x480! Still 24PPD
