The function dpu_plane_sspp_atomic_update() updates pdpu->is_rt_pipe flag, but after the commit 854f6f1c653b ("drm/msm/dpu: update the qos remap only if the client type changes") it sets the flag late, after all the qos functions have updated QoS programming. Move the flag update back to the place where it happended before the mentioned commit to let the pipe be programmed according to its current RT/non-RT state.
