Image quality improvement on 1080p or lower resolution content

I am using Apple TV with Infuse for couple of months, while the image quality of 1080p is not as good as the other player, e.g. KODI on Sony TV.

Finding:
Once i set the output resolution of Apple TV to 1080p/60hz, the image quality is much better on 1080p video, sharp and clear, i mean as good as other player.If set to 4K/60hz, the image quality while playing 1080p video will be degraded.

Analysis:
My TV is Sony OLED A8f, my assumption the TV OS has optimization on low resolution content, such as 1080p video. Thus image quality is improved while AppleTV output as 1080p/60hz.

Suggestion
Is there possibility to adaptively set output resolution by Infuse, according to video original resolution. This will be helpful to leverage the optimization from TV/Display, making IQ better.

Thanks,
Yasoo

Apple does not allow for dynamic resolution switching. All apps have to use either apples or their own upscaler
