The 4 Jan '24 Amazon customer review said it was ok for their 55inch curved tv, so it would seem compatible for your need.
The screws for back of tv are not usually supplied with the mount. They should be in the tv rear case already from the manufacturer
i have the exact same 1 for my 65" and it did the job.
it looks like it comes with all fixings including wall plugs.
have a look at currys online though mate. they do some good ones around the same price with all fixings.
the only thing i will say is they tend not to hold the tilt where you set it for heavier tv's, so i had to put some smalls screws in the bracket to stop it moving to full tilt.
