but if you compromise a mining pool operator and you use their miners than there will be an instant reaction and correction to stop such an attack from re-occurring or happening in the first place
Unless you have a time machine, you can't tell which mining pools will attack before it happened.
(only if you independently verify you have found a block, but the pool does not broadcast it. This is unlikely, because most miners check the stats of their miner on the pool website, which could be faked.)
Realizing your pool attacks and switching miners to a different pool is not instant.
