It's not. I wrote it on my own. Want to make a bet before telling such absurd statements. How about it?
That makes no sense whatsoever. And IMAX resolution has nothing to do with cinematic experience, since there is probably just 1 pure IMAX in India to speak. It's very likely that you have never seen true IMAX anyway (digital IMAX doesn't count).
75" TV will not look sharper than 55" one because while it's further away, it also has lower pixel density. That gets exactly compensated. Both have the same 3840x2160 resolution, but it's stretched thinner on the 75".
Did you flunk maths? A 55" TV has smaller pixels than a 75" TV by the same proportions. So while they'll look bigger, they will be the same size as a 75" one at proportionally higher distance.
Go search about what a steradian is, pixel pitch and projection angle.
