While testing out auto-mode-switching in tvOS 11.2 in Infuse and MrMC, I found a possible issue with HDR content. I found that Infuse switched my TV to HDR, but it output an SDR image. In comparison, MrMC also switched the TV to HDR, but showed HDR output.
I tested the Life of Pi sample:
And the Digital Foundry Gran Turismo Sport sample:
Even with the Apple TV forced to 4k HDR, the Infuse HDR videos were washed out when compared to MrMC. They looked like the typical HDR -> SDR conversion.
Is this a bug or am I doing something wrong?
