I use a Frame and don't have any of the issues you describe in the slightest.
The power button turns the TV on with a 0.5 second animation, and immediately I see the Roku interface with no popups or Samsung branding or anything.
Probably the ONLY complaint is that by default my washing machine puts an alert on the TV every time it's finished.
I would probably find the setting to turn it off but honestly part of me finds it very cool for my washer to creep onto the TV because it knows I'm watching.
EDIT: maybe you are using wifi? It's the only thing I can think might be different in my setup. Try running RJ45 and see what happens? All I can say is Works On My Machine unless you add some details
