Sounds like a market for premium "TV backdrop" accessories to improve viewing comfort.

We have a lot of pure black substance (and paint) but again this is solving a problem nobody really has.

Perhaps combining a transparent display with a pure black gives better blacks for displays but until there's better color control this would result in a much worse television.

While backlit LCDs always had a bit of a problem on that front, normal OLED screens already offer true black.

Only in a darkened room. While OLED blacks have zero light emission they do still reflect a bit of light.

And qd-oleds rather a lot of light.

Samsung and LG have the problem of how to to create the next desirable product.

3rd parties will sell spray cans of pure black paint that you can use to improve the back of your transparent TV...

Or they can add an e-ink panel behind the main panel(s).

TV manufacturers will then detect this and remotely lock the user's TV for breaking their ToS.

And miss out on ad revenue? No, they'll just silently mark your warranty as void and continue to force feed you and your family targeted advertisement while siphoning out all the private data they can gather from your living room and your network.

Or the front of other's transparent TV's used to advertise to you.

Why not just a curtain of black fabric? Spray paint requires some skill to apply consistently and without waste, whereas a clip-on fabric is far harder to screw up and less likely to void your warranty.
