If ur tv is larger than 55 inch u can appreciate better picture quality from 1080p to 4k otherwise there won't be significant difference and one more thing is viewing distance.U can appreciate the quality if u seeing from less than 10 feet.
I feel now a days Jio 4k picture quality looks better than star 4k ( airtel dth ) in my sony 75 inch tv but during IPL star 4k felt better than jio 4k.
