Bug in Nvidia Optimus - CPU reports high power state when dGPU active - Blade 15 Base 2019

Whenever any program attaches itself to dGPU the CPU package power increases by 10W. I don't really see a drastic change in temperature, not sure if this is just sensor value or real power usage, but it definitely affects power limits. Even something like Steam webhelper attached to dGPU will cause reported package power to be 11-12W, while laptop is idle with CPU at 800MHz. The easiest way to reproduce negative result is just to have Intel Power Gadget running, and run Cinebench R20. It attaches itself to dGPU by default, during benchmark (in "Creative" Synapse mode) after the CPU gets down to 45W the clock will stabilize at ~3.2GHz, final score around 2600. After forcing the use of iGPU by CB20, restart it and then the clock is ~3.6 GHz @45W with final score close to 2900. This occurs on both the 419 drivers as shipped with laptop and the 431 drivers published here a week ago.
