I did some testing and measure (with a colorimeter) on video test patterns on Infuse, Plex, Home sharing app and LightSpace Connect (which is a TPG - Test Pattern Generator - app), all on my Apple TV 4K 2nd Gen (2021). The results were that the TPG app, Plex and Home sharing have the same outcome wh…

[image] Anger: Does Infuse use a proprietary player Yes, Infuse is a proprietary player. You may want to run your test video through mediainfo and post the results here. That would help to answer your questions. When you ask Does Infuse modify the source content? Do you mean does it act…

Of course I did not mean that. As the measured values of the patterns displayed via Infuse are different from the other apps, there must be some sort of manipulation (done by the proprietary player) slightly altering the original/intended output (RGB values of pixels), resulting in a ~5% brighter an…

mediainfo returns information of the media file. If you want I may verify the difference with a pixel analyser.

This is interesting…and not so good if confirmed :grin:

No James, the test patterns (21 grayscale patterns - in 5% steps) I used are SDR. All of the TVs/monitors (LG OLEDs, Acer/Dell PC monitors) to which I connected my 2nd generation ATV4k give the same results: increase in luminance and y-values (in the CIE diagram) across all scale except 0 and 100%. …

The issue could be that Infuse internally converts video scale (16-235) to PC scale (0-255) and that causes a luminance mismatch in the final result. I’d run more investigation on that if I had the time…

Without knowing more details about the test content, the Apple TV settings, and the device you are connected to I can’t really offer an explanation for what you are seeing.

But it could it related to this, which affects certain content types.
