Strengthen HDR Config Protection enforcement with EDID override

[waydabber]

I have been using BetterDisplay Pro (1.4.6 Build 14593) now some weeks, every time I connect the computer to the TV (my main monitor) I need to re-enable HDR. I have set Config protection to keep the HDR setting but it does not work for me. After reconnecting the TV, the HDR is disabled. It shows a toggle in HDR config protection but it is "Protect HDR Status (HDR Off)". When I set manually HDR On, config protection shows the correct toggle "Protect HDR Status (HDR On)". But again, when the TV is reconnected, protection has changed to "Protect HDR Status (HDR Off)" and HDR is disabled.

Protection for Resolution and Refresh rate is working fine. I'm not sure if this could be related to the fact that I have set Configuration override to default resolution 2304x1296@120hz that I'm using. Would it make sense to add HDR to the configuration override?

Let me know if you need some log files, etc.

Hardware:

• Macbook Pro 14" M1
• Cable Matters DP->HDMI Adapter 201388-GRY with Chip VMM6100
• TV Sony A80J OLED, customized EDID to support 4K@120hz HDR 4:4:4
