Does anyone know why does checked-in luggage presents more risk than carry on (presumably). Is it temperature and pressure difference or just visibility and acc

  Just visibility & accessibility. Checked baggage is packed in tightly along with other combustibles. If you start a fire in the hold, it'll spread too quickly to detect, let alone extinguish. https://aviation.stackexchange.com/questions/9626/is-it-possible-to-access-the-baggage-compartment-in-flight https://aviation.stackexchange.com/questions/9626/is-it-poss...

  “...if a laptop [battery] catches fire in the cabin, it will be noticed immediately and steps can be taken to put it out. And though there are fire safety systems in the hold of an airplane, they aren't well-equipped to deal with the type of fire that lithium-ion batteries generate.” https://www.consumerreports.org/electronics/problem-with-stowing-lithium-ion-batteries-on-planes/ https://www.consumerreports.org/electronics/problem-with-sto...

  There's no way to send "someone with a fire extinguisher" to a cargo hold of a modern commercial airliner while in flight (Edit: limited access exists in some airliners, still not something you want to crawl through with a fire extinguisher). The holds do have fire suppression systems, but modern batteries pack a lot of energy, and the extinguishers might not be sufficient. Plus, the holds are literally crammed full, further hindering any firefighting efforts.
