Is HDR broken in Pr 2022? 2100 HLG with HEVC 10bit 4:2:0 blown out ?

[Rob Ainscough]

Source is iPhone 13 Pro Max with 4K 60 HDR recording, looks GREAT during playback on my iPhone.

Export the MOV to Pr 2022 and load Pr and it looks terrible, whites are blown out.

I've verified Adobe Pr settings/preferences:

• Display Color Management = checked
• Extended dynamic range monitoring (when available) = checked
• Optimize rendering for: Memory

Sequence Settings:

• Apple ProRes 4444
• Max Bit Depth = checked
• Max Render Quality = checked (this settings does NOT save??)
• Composite in Linear Color is grayed out???

I've tried my monitor at 8 bpc Full range RGB, 10 bpc Full range RGB, 10 bpc YCbCr422 and YCbCr444 and this settings make no difference if output (white still blown out).

In addition, when I check "Max Bit Depth" and "Max Render Quality" I get a warning about setting Optimize rendering for "Memory" when it already IS set to "Memory"??

It feels like HDR in Pr 2022 is VERY broken, is it just me?  Anyone else successfully worked with iPhone 13 HDR video at 4K 60 FPS in Pr and it looked good?

GPU is an nvidia RTX Titan 24GB VRAM with latest nVidia Studio Drivers (not game drivers) v512.59.

FYI: I did check Kevin's post here and I'm last option working in HDR with HDR and an HDR monitor/cable with HDR capable GPU with my OS set for HDR.

It's definitely a bug ... but it's because you have ..

...Using hardware accel... 

By @movingimage

If you switch over to software rendering then that option will stick.  The issues seems to be Adobe understanding the various GPUs (and drivers) and what they can and can't do ... anyway, side point, Adobe should simply NOT show the option if the GPU hardware isn't able to support the Max Render Quality option ... allowing users to check this option but ignoring the user input because of hardware acceleration is just going to trigger confusion and more support questions.

I'm not sure what Hardware actually support Max Render Quality but I'm guessing something very expensive and exotic as you definitely do NOT want to be rendering as software as that will take forever and a day pending project and encoder.
