First of all, you don't need an OLED monitor. Most computer monitors are not OLED. Terrible use case for OLED.
All you need is an IPS panel. If you want one with wide color, plenty of those exist. Also, it is pretty funny to see you talk about "color accurate" in relation to this and thinking you're going to use a TV. TV's are terrible at producing color accuracy for computers. Take any TV and 5 of the cheapest computer displays you can find and all the computer displays will be more color accurate than the TV.
You're off on completely the wrong trajectory. There is no shortcut that allows you to save money by buying a TV instead of a computer display, and get good quality out of it. There is a reason why no TV has a display port in. There is a reason why people have computer monitors on their desks and not TVs. You haven't stumbled onto something that no one else has thought of it. TV's are too large to sit close to, are not meant to show static content all day long, have low resolution compared to physical size, have poor color modes for computers, etc. etc. etc.
