Hi. I understand the potential confusion but the answer is really relatively simple. The fact is that you calibrate your display device to various industry defined standards for SDR and HDR content. DVD, Blu-ray or Freeview or Sky Q all share the same SDR industry standard. Same too for HDR capable devices. Unless you have a faulty source device or your source device is 'fiddling' with the output you should get exactly what the content provider is sending on your calibrated display device. So we simply need to make sure that your source devices are passing the content without fiddling with it.I've got a few questions about professional calibration.
1) Most of my devices actually go in to my Denon AV/R
4K Blu-ray Player
Xbox One X
Surely every device is different, so how can you calibrate the TV correctly in that scenario?
2) If it was all calibrated and then I upgrade/changed the AV/R in future - would it need re-calibration or do they all literally just 'pass-through' the signal purely without additional processing?
