The RTX video upscaling feature works really well, there's a bug in the Firefox implementation that allows you to switch between native and upscaled side by side and the difference is striking. I don't have an HDR monitor so I can't tell you how well this new HDR feature works.
I don't think making things up is the problem, it's if it's believable. If it's indistinguishable to a viewer, then who cares. I never would have thought the HDR of the clouds was "made up".
I would use it on every single video I've ever made myself, because intent had nothing to do with how my videos look. They were made with then best camera I had available, and HDR has only been available relatively recently.
This is a tool that I want to use. If nobody can tell I used it, that's a good thing for me. If you don't want to use it, then nobody is making you.
