Why always when I read some bytes from bytes32bytes32 only first read return a value, all following will return zeros? 0x00

bytes32 proof = 0x999e7640514e578f5b9b416469d270d559ad4186ef63da6cd63751373512735e;

bytes1(poof[0]); // some real value, e.g. 0xf2
bytes1(poof[1]); // all following are zeros, e.g. 0x00
bytes1(poof[2]); // all following are zeros, e.g. 0x00

No matter from which index I'm started. Solidity docs says per-byte [] is read only, so what is explanation for such output?

Reading bytes from bytes32 returns zero value (except first one)
