Netflix 4K on a 2K screen?

I just signed up for Netflix Premium with UHD 4K. I do not own a 4K screen, but wanted to try an experiment.
Could I get 4K to display on my 2K screen while running NVIDIA DSR and setting the higher screen res.
I wouldn't expect the display to look as good as it would on a true 4K screen, but perhaps it will look better than 1080p running on the 2k monitor, which is what I am getting if not streaming 4K.

My screen (Asus Tuf Gaming VG27AQL1A) is HDCP compliant, and when I check the HDCP status in NVIDIA CP, I see that the system is HDCP compliant. It does not say what version of HDCP.

Apparently, this method of 'cheating' 4K works with games. I do notice that when DSR is turned on and resolution is increased, I do get a smoother image.
However, from what I understand Netflix and other streaming services can be very picky as to what qualifications they look for on the device before setting streaming quality.

Thanks for your help

It will be down rez'ed to 1080p. Doubtful you would notice the difference between 2160p and 1080p on a 1080p set.

The application will determine what it's outputting to & act accordingly.
It will also take into account what it's being played from, in my experience.

For instance, I can't get HDR in Hulu from my LG's internal application, but I can from a Roku-Ultra.
When my screen is set for native res (2560 x 1440), I see only 'HD' in the Netflix description of the programs that are available at 4K, whether running Edge browser or the Netflix Windows app.
But if I set res to 5120 x 2880 (I think it works for 4434 x 2494 as well), then I see '4K Ultra HD'.
While I understand that I will not get true 4K on my 2K monitor with NVIDIA DSR, I thought perhaps I would be streaming at 4K and down-sampling to the 2K res.
That said, I have to agree with vb47 in that I don't notice any difference between leaving the screen at its native res, and using the DSR at the higher res.
So I guess if I really want 4K, I'll have to upgrade to a 4K screen!

Still, I do get better results with games.
I have one particular game: Run8 Train Simulator V3, in which I am seeing 'jaggies' on the tracks.
This has been an issue with Run8 since V2 (and I'm sure V1 but I don't go back that far with this game).
When I use DSR to increase res to 4K (5120 x 2880), those jaggies disappear.
Of course, my RTX2070 Super 8Gig is running at nearly 100% with the higher res, but the game plays smoothly.
I guess the same does not apply to streaming video.

I have a QHD monitor that will display in HDR, but it also will do UHD at a lower FPS.
As far as I know, the streaming applications won't recognize the in-between, QHD.
