That is true, however the purpose of highDpiScaleFactorRoundingPolicy is override the system setting. For example, a Windows display can be configured for 175%, but the app knows it does not support that and has enabled rounding (to 200%). So if QT_SCREEN_SCALE_FACTORS is considered a system setting then this is an inconsistency in behavior.
