Quick clarification In NVIDIA App 11.0.6

Quick clarification In NVIDIA App 11.0.6 with the DLSS Overrides enabled even if a user selects Preset K (DLSS 4.0 model) the DLSS 4.5 Super Resolution engine/runtime is running under the hood, correct? Does this mean that Preset K still benefits from the 4.5 SR improvements like smoother temporal stability and better upscaling, even though the model label hasn’t changed?
