Application icon size for Tizen 8 (One UI)

Hello,
I’m developing my first Web app for Tizen TV, and I’ve deployed it to my S90C, but no matter what resolution I choose on my icon it has blurry scaling artifacts.

Do you know what the correct size for icons (icon.png) is? I’ve searched all over the guidelines, the only specification I’ve found for TV is for store banners, not icons in app menu.

I’ve started with the default (106px) in demo project and multiplies of that, all were distorted.
Then I tried some classic sizes (power of 2), 512px, 256px, 128px (out of these probably best was 128, because downscaling seems to be terrible).
I’ve also tried putting in a icon.svg and specified that in the config.xml, but in that case no icon was shown.
I’ve even found specification for config.xml that said <icon> element accepts width and height property, so I tried with 512, 256, 128, 64 all at the same time, but it only used the one named icon.png

All answers are appreciated.
