Closing HDR Switch after an HDR game was closed is not turning HDR off

Seems HDR Switch does not have control of HDR setting after you launch an HDR app.

To test this I tried the following:

1- Manually set HDR to OFF
2- Run HDR Switch --> HDR turns ON
3- Run HDR game
4- Close HDR game
5- Close HDR Switch --> HDR is not turning OFF

I'm going to try and understand your code, but to me it seems that a new "hook" must be done to regain control of the setting

the nvapi hook is meant to be used by game developers
if what game is it that you are running? it might have something funky going on that hard enables it -- the nvapi version only works while the app is running but there is a registry key that can be used to enable it afaik

This is happening mostly with Red Dead Redemption 2 and Call of Duty Modern Warfare.
Seems like the game "takes over" and then HDR Switch is unable to change the setting to OFF when it gets closed. I need to test the behavior on the tray version and see if it still happens
