does changing withdrawal method after a win make online casinos review you harder?

so here’s the thing, last week i hit a decent win on live roulette and decided to swap my withdrawal from the e-wallet i usually use to a bank transfer, mostly because the e-wallet fees are getting silly. now i’ve got this feeling they’re eyeing my withdrawal harder, like suddenly i’m a high-roller or doing something sketchy. they did ask for some extra docs but nothing crazy - just “routine” stuff they say.

i know casinos are always looking for an excuse to dig deeper, especially after a streak or if you use a promo bonus, but does switching the method after a win flag you? not in the tinfoil hat way but more like is this a known pattern for triggering a longer review? anybody else seen slower payouts or extra checks just for trying a different withdrawal after a win?
