Different between webOS_TV vs webOS_OSE

Hi everyone! I’m new to webOS.
Currently, I have been trying out built-in apps in webOS OSE by following the Developing Built-in Native Apps guide.
I’m not sure if webOS TV is the same. According to the guide, webOS TV uses webOS Studio and webOS CLI for development, which I believe is primarily for developing web apps.
Am I correct? Can I build a C++ app like I do in webOS OSE and use it in webOS TV?

We do not guarantee the compatibility of webOS TV apps with webOS OSE resources. For webOS TV apps, please use webOS TV resources in this website only. Thank you.
