I see, so as i suspected it's a matter of if they check and which situation we are talking about.

Correct.

It Is evaluated on a case-by-case basis.

What about amazon warehouse instead? Would the success rate in my case actually be higher?

Given Amazon Warehouse Deals are second-hand/used Items and the fact they do not keep their Inventory up-to-date, on these grounds, the likely hood of a successful SE Is certainly more so than not.
