answer - Nope

function loopCheck1(uint256[] memory arr) external returns (uint256[] memory) {
gas = gasleft(); // 29863 gas
uint length = arr.length;
for (uint i; i < length;) {
unchecked { ++i; }
}
return arr;
gas -= gasleft();
}

function loopCheck2(uint256[] memory arr) external returns (uint256[] memory) {
gas = gasleft();
uint i;
uint length = arr.length;
for (; i < length;) { // 29912 gas
unchecked { ++i; }
}
return arr;
gas -= gasleft();
}
