Only thing I can't quite figure out though is I want to have 3840x2160 @60hz on the desktop and 1920x1080 @ 120hz in games. I have been able to get 120hz working by creating the resolution and setting my desktop to it. When I load a game it maintains 1080p120. However if I set my desktop to 4k60 and load a game, selecting 1080p defaults to 60hz and most games don't show both res/hz as options.

I tried modifying the existing detailed resolution to be 1080p120 instead of creating an additional entry. What else can I try? I'm tempted to clear the entire list from my extension block "TV resolutions" tab and leave only the 4k60 and 1080p120 entries.

Some games use the desktop refresh rate, and the graphics driver will automatically propagate the refresh rate for the native resolution down to lower resolutions as scaled resolutions. Try 1920x1080 @ 120 Hz as the first detailed resolution and 3840x2160 @ 60 Hz as the second detailed resolution. Then delete all the other resolutions. All you need in the extension block is HDMI support, HDMI 2.0 support (or 4:2:0 resolutions if using HDMI 1.4), and audio formats if you want audio sent to the TV. Make sure to delete any resolutions in the HDMI support data block as well because that's where 30/24 Hz tends to be.

Well that worked great, and so easy. Some games seem to be defaulting to 4k on opening or acting gibbled and running some bizarre scaling in full screen mode but setting borderless window in that case fires it into 1080p120. Any games that don't support it seem to scale up to 4k (according to the tv's signal indicator) but have performance of 1080p at a glance so I'd assume that's not something I will care about.

All in all, I can dig it. Minor quirks are minor and your method worked perfectly. Only extra step I took was to set 1080p 120hz as native resolution in the TV res list (I think that's where I came across the setting)

Edit: I'm also getting a resolution error response on the receiver when toggling between 4k and 1080p120, not a big deal.goes away after 5 seconds or so and works perfectly fine. Might need to play with scaling to get it back to switching without complaining like it was before
