Internal Grabber Colors not as bright as from Colorwheel

Yesterday i updated my Rpi with recent stable release of Libreelec and the newest version of Hyperion.

If i select a color in my Colorwheel and sent it to the RPi via SSH e.g.: R.255 G:0 B:0 the red (LED brightness) will be much brighter compared to if i select a completly red image and use the internal grabber.

the red grabbed internal from a total red image (R:255 G:0 B:0) would be approximatly equal to a red from the colorwheel with the values R:128 G:0 B:0.

-the rainbow swirl at start is also working as supposed

Using: Rpi2, Libreelec, WS2801

configuration:

thanks for help in advance,

ok i figured it out by myself now. I first did a fresh install of Openelec instead of Libreelec. After that installed Hyperion again and it was working partly.
Last thing i had to do was disable the Black Border Detection in the Code manually, since LEDs on top wouldnt turn on.
