The Issue

The overall image quality in the Samsung TV app is very poor. This is because the TV App requests every image (thumbnails, backdrops, posters, actors, photos, ...) with too aggressive JPEG compression from the server. It always uses "quality=50" in every request for any image. Please see examples from the log below.

 

The Web app does not suffer from this issue as it request every image with quality=90 instead, which is perfectly fine!

 

Please, improve the image quality in the TV app by setting this parameter to 90, just like in the web app or let me choose in the settings.

 

 

Examples

Here are some examples of poster images directly requested from my emby server, the left one with the tizen app settings and the right one with the web app settings.

See the massive artifacts in the background of the first example the heavy color bleeding around the title in the second example.

 

Please, also keep in mind, that this compression artifacts are much more visible on a big, high contrast TV screen than on the average, standard contrast PC / smartphone / tablet screen you're probably reading this post on right now.
