Tried it here again but using older madVR Mediaportal build (1.16pre-release) which remains in sync both with stock settings and when using NGU + SSIM, however do have a new Atmlight build you could try so attached it here.
Unfortunately this build is not working for me at all
The moment I activate the LEDS they remain static with the color that was on screen during the activation, if I switch madvr to full screen exclusive mode then the LEDS do not work at all, not even the initial color is being shown.
