I work for an ISP and have user-facing support tickets for "slow speeds on Playstations" happen. First thing we do is pop the hidden browser on the console (if it's a PS5, where they decided to "remove" the browser) and run a speed test and it'll pull full rated speed of whatever service we throw at the user. I can pull full wire speed from North America to Cape Town on a Playstation but god forbid you try to download from PSN in the same country. Doesn't matter what DNS we've used - be it our internal, Quad9, etc.
