Stop exaggerating. I have youtube on tv, and can also put ps4 games there, 1080p doesn't look that much worse than 4k. The ps5 is a different beast, the 4k videos do look notably better than the 1080p stream, but that might have had low bitrate.
I am not exaggerating. Assuming you have a 6" phone screen 144p will have approximately 20% more PPI than a 55" 1080p tv.
And wait, have you never even seen a game running natively at 4k? You are just basing this all off of youtube streams?
