Can the drywall really handle the load?

The problem is not the theoretical load per screw, but that there will be lateral shear forces every time you adjust the TV since the screws are all in a line. Eventually, it will start to loosen, and the screws will begin to eat into the drywall.

The bracket mattoys shows is much better.

The mount mattoys shows is much better.

I would test it on some non-essential area to get a feel for the forces.
Remember, it should look nice too... And that other mount doesn't.

If you think the mount is ugly, you have a TV that's too small.

If you think the mount is ugly, then your TV is too small.

The purpose of the mount is to get the TV out from the wall, and it will be visible from some angle regardless of the number of inches.

Attach a plywood between the studs where the TV will be mounted. Paint/wallpaper it the same color as the wall. Securely attach the bracket to the wall.

If you want to do it seriously, cut away the drywall, insert noggings, put the drywall back on, and paint.

In your case, I would replace the drywall with a similar fiberboard that can withstand much more load. Sure, it’s more work but no headaches later when you have heavy loads. If you want to maximize what you have now, I recommend watching the following test of fasteners:

Alternatively, cut a narrow hole below where you plan to attach the bracket. Insert a plywood board into the hole and secure with screws. Then, of course, there will be spackling and painting.

A thousand thanks for all the wise answers and ideas. In a newly moved-in apartment, I chose the easiest way: There was a brick wall next to the drywall, and with my arm maximally extended to the side, I could mount the TV on it and still have the TV in the right position in front of the drywall.

Grateful that I didn't mount it on the drywall - I now feel the risk of it collapsing is sky-high.

All's well that ends well.
