Painted Wall As A Home Theater Screen vs Traditional Screen Fabric

I currently have a Da-Lite 16’ x 10’ ......Da-Mat Half Angle: 60° | Gain: 1.0 screen.
The screen hangs from a 22 foot ceiling.

I am contemplating painting a 20’ x 11’ wall with some type of screen paint as a new projection screen.
I am able to make the room completely theater dark.

I’m currently using a 4,000 lumen short-throw 1080p projector.
I have no plans of going to a 4k projector in the near future because of the cost is currently prohibitive for short-throw 4k with 4,000 lumens that can throw an image this large.

Does anyone here have any experience with painted-on movie screens vs a traditional fabric screen?
Can a painted-on screen look as good as the Da-Lite screen that I’m now using?
Any suggestions with paint that you’ve actually used with great satisfaction?

The paint will have to be applied with a roller...I can’t use a sprayer in my living room.
