We have reached new levels of “remaster of game that already looks great and runs well”
That’s a “port”.
A “remaster” is traditionally more focused on a rerelease with improved graphic fidelity - details, resolution, possibly lower-effort improvements to models and geometry, but basically the same game, slightly modernised with better modern compatibility.
A “remake” would be a complete overhaul of the modelling, QoL improvements, or reimagining some systems potentially including game engine. Eg, the FF7 remake.
