Hi Luke,

So here's how it goes:

1-You switch on the PS4, the colour profile is the default one (no HDR in effect yet)

2- The menu looks normal (baby blue).

3-You launch a HDR game or program (HDR mode is on).

4-colours look normal as long as you're watching the HDR formatted content.

5-You press the PS button to go back home.

6-The screen is still in HDR mode, so the menu will look pale.

I've seen this effect on my phone which supports HDR when I go home while watching a HDR program on Netflix.

I hope this helps.
