Samsung UE37ES5500 and folder thumbnails

Hi everyone, first post so may I just say what a great product Serviio has been for me so far.

I've got 2 Samsung TVs which I believe are D series.

UE32ES5500 and UE37ES5500

I simply would like to know if they support a folder thumbnail instead of the "yellow" folder that's currently displayed?

My setup:

Serviio v1.2
Samsung TV latest firmware
I use Folder view only
My structure e.g.

FILMS\In Time\In Time.Mkv
FILMS\In Time\In Time.jpg

Thanks in advance
