Yeh, but the issue isn’t frame rate fluctuations. The issue is flicker relayed to how OLED panels work with VRR.
There is one situation that perhaps could be grounds for a return and that's flicker caused by the refresh exceeding the VRR range. It's not that common but some OLED screens have an issues where when VRR is engaged the screen will actually exceed its refresh rate ceiling and when it does this it causes flickering
Here is an example, it's a 144hz Samsung OLED screen and the user has the framerate capped in the driver to 120.
Look what the refresh rate does with VRR turned on. On screens where this happens it creates flickering
