You might be looking for a unicorn that poops diamonds and rubies. I'm not sure many if any companies manufacture comparatively small televisions with built-in Blu-ray players.
The mount is almost certainly a standard VESA mount that will work with virtually any new television of a similar size. (Four screws in a square, either 75mm or 100mm apart.) If by some oddity it isn't a standard mount, there are a multitude of wall and ceiling mounting brackets available for these standard TV mounts, so it shouldn't be at all impossible to find one that would work for your installation.
