Multiple Xbox Series X Problems - Looking to Crowdsource Answers

I tried reporting these and posted on the Insider Forum on Reddit, but the thread was deleted as they are "general issues."

Here are a few things I noticed after switching over from an Xbox One X (X1X). My XSX is connected to an LG C9 (as was the X1).

1. Smart Delivery - I had Ori and the Will of the Wisps downloaded on an external (USB) hard drive from my X1X. When I plugged the external drive into my XSX it (along with many other games)
   immediately updated. I assumed this was the update for the "Series X Optimization." After the update, I moved the game to the internal drive and booted it up to experience some 4k/120hz action and was met with an in-game message stating that "120hz was not
   supported on my device." I had to uninstall the game and redownload it directly to the internal drive to get 4K/120 to work. Bottom line, legacy versions of games that were optimized for Series S/X have to be redownloaded directly to the internal drive. You
   can't transfer from external drives and get the optimization unless the game was originally downloaded directly to the internal drive. After the fact, I guess this makes sense, but I'm guessing there are going to be some confused gamers.
2. "Allow 4K" Option - On the X1X, I had my resolution set 1080p and had the "Allow 4K" option selected in the Video Settings. This way, 1080p content would not be upconverted to 4K, while 4K would display
   appropriately. This doesn't appear to be working on the XSX. With the XSX set to 1080p and "Allow 4K" selected, both Ori and The Touryst (two XSX optimized games that support 4K) were only displayed at 1080p. Only when I changed the console resolution from
   1080p to 4K UHD did I get 4K in either game.
3. VRR, ALLM, and Streaming Video Apps - On the X1X, if you had VRR and ALLM selected in the settings, the X1X forced all video streaming apps into ALLM/IGR (not just games). When VRR was off and only ALLM was selected,
   IGR worked correctly and only engaged during gaming content. I did a detailed write-up on this here. Unfortunately, this was
   not fixed with the XSX. I will continue to use the C9s built-in apps for all my streaming (Netflix, Prime, etc.)
4. Auto HDR - On some games, Auto HDR appears to be engaging where it shouldn't. One example is Tetris Effect Connected. This game supports HDR, but it is turned "off" in the game setting by default. Thus, when you boot the
   game the first time, you are met with XSX generated Auto HDR that is retina-torching bright. If you go into the game settings and set HDR to "On," it will change to the proper, developer-intended HDR. Why would Auto HDR engage on a game that supports HDR?
