4K Tizen Movie Posters low resolution



I have a conundrum. I have a 4K MKV HEVC library ripped in full UHD Blu-ray quality (not compressed/transcoded). But...

My 4K Apple TV displays BEAUTIFUL high-resolution poster art for my movie library, BUT my 4K movies won't play back d/t transcoding. (Even my 1080p movies look only fair d/t transcoding.)

My Samsung UN82MU8000 direct plays these 4K movies AWESOME, super smooth, no buffering, BUT... the posters are very low resolution and look TERRIBLE.

Could we please display high resolution movie posters on the Plex Tizen app? Please?
