Embedded report memory consumption

I will echo lbendlin and say that you'll most likely want to try and optimize your Power BI model. Without knowing the specific TV models, it's difficult to say why some TV models can load the report and others can't.

Not sure about the 200 MB question either, unfortunately. I know that my Power BI reports can be significantly large sometimes just depending on the report's use case and whether I'm using a shared dataset, Import Mode, Direct Query, etc.

If you can use a DQ connection to a shared dataset, that might alleviate some of the RAM consumption, but I'm not 100% sure on that.

If you don't end up finding a solution for your problem, I will throw out that I've made a custom Power BI app for digital signage called Displagent. Works cross-platform, too, so if cost is an issue, you can purchase a Raspberry Pi Model 4 that will work very well with it. Has a lot of advanced features beyond just loading a plain report on a screen.

Hope some of that helps!
