@itsage, I made a script to delete duplicates (it ignores the first 128 bytes which is a header containing creation date). I still have multiple profiles for the same display - maybe a display has multiple inputs (DisplayPort, HDMI...) which get different profiles? Or maybe new macOS versions will have new tags?

@joevt, Thank you for sharing this script to remove duplicated monitor profiles. On my Samsung CHG90 monitor for example, there are three preset buttons besides the four inputs. I observed changing either monitor inputs or presets would result in a new profile. I typically switch from eGPU monitor input to iGPU/dGPU input during macOS system updates once every few weeks. You can imagine it gets out of control rather quickly.

I removed prefer HDR option since my LG 27" HDR (I think 27UK600) looks like washed crap.

@itsage, does the color information in the EDID change for each preset? Download, make, and install edid-decode. Use the script at https://gist.github.com/joevt/32e5efffe3459958759fb702579b9529 . Follow the instructions. Execute loadagdc after each preset change, then when done, execute listedids, decodeall. List the resulting files with "ls -l". Compare the results of *_decode-edid.txt if there is more than one.

Recently, I picked up an inexpensive LG 27" 4K display with HDR10 (LG 27UL500). It's connected via DP cable to my eGPU setup.

I've been pleased with the way this LG model displays HDR content (imported from my iPhone Camera Roll) in the Mac OS Photos app.  

Also, I've found 4K HDR music videos running in YouTube using the Chrome browser look comparable to the same video when displayed on my living room 4K HDR TV setup. 

I wasn't expecting to make use of the HDR mode option in 10.15.6. But so far I've been happy when enabling it to consume content in Photos and YouTube.

Yes when they added HDR support to chrome in MacOS, I've been able to switch HDR mode on and watch them, and they look the same as in bootcamp.  I wish the itunes store/apple tv content would play in HDR though, and I also wish the desktop would map into the HDR color space properly without being so washed out.
