With distance to tv at 4.5m, is it right to say i need to go with at least 75inch tv?

currently owned Samsung OLED TV. I am exploring X90L, LG QNED86 at the moment. Or without burning holes to my wallet, there are xiaomi mini led (spec wise looks quite good) or tcl. I am trying to keep at 6k budget, but open to top up if it is good cp.

Usage wise mostly for movie, with some future consideration of gaming.

Will be good to get some opinions from lyn pros
